Pragmalinguistic and syntactic features of interjections in the Kabardian-Circassian language
Authors: Afaunova Andgela Anatolevna
Published: April 2023

The aim of the research is to identify the pragmatic potential of interjections of the Kabardian-Circassian language from the dialogical, pragmatic perspectives, i.e. their roles in encouraging interlocutors to engage in dialogue and forming communication. The scientific novelty of the paper lies in the fact that the pragmalinguistic analysis of interjections of the Adyghe languages has become the object of research for the first time. The paper is the first to determine that the main function of linguistic pragmatics of these expressions in the Kabardian-Circassian language is choosing a certain interjection in a specific speech situation. Interjections occur in different positions in a sentence (at the beginning, in the middle or at the end), which also conditions the degree of expressiveness of an utterance. The research findings have shown that interjections perform two main functions in utterances: the manifestation of an emotional attitude and the establishment of communication, thereby confirming the inseparable connection of their syntactic and pragmatic roles. It has been proved that an interjection is added to a speech act unconsciously and depends both on the personal qualities of the speaker and on the level of emotional intensity of the situation. One of the main features of interjections is the ability to carry the semantic load of the entire utterance while replacing the whole sentence.

Phonetic interference in the speech of the Vietnamese studying Russian
Authors: Novospasskaya Natalia Viktorovna , Phan Nguyen Hanh
Published: April 2023

The paper contains a comparative analysis of the systems of vowels and consonants of the modern Russian and Vietnamese languages. The aim of the study is to suggest a classification of interference facts at the phonetic level in the speech of Vietnamese students in the process of mastering the Russian language. The paper identifies the main differences between the Russian and Vietnamese languages at the phonetic level that are related to the quantitative and qualitative discrepancy of consonants and vowel phonemes, to the peculiarities of syllable organisation, as well as to the presence of tone in the Vietnamese language; the mechanisms of error formation in students in the process of learning Russian are identified and analysed. The study is novel in that it is the first to clarify the connection between interference and the process of adaptation of words of French origin in the Vietnamese language. As a result, the phonetic errors of Vietnamese learners studying Russian are proved to have a close connection with the borrowing of French vocabulary into Russian and Vietnamese, as well as with the strategy used when adapting borrowings from French in the Vietnamese linguistic environment.
Internet slang in virtual communication as a linguistic phenomenon
Authors: Guo Jingyi
Published: April 2023

The aim of the study is to identify trends in the development of Internet slang caused by transformations in the field of politics, economics and culture. The paper discusses the features of Internet slang functioning in the communication of Internet users. The formation of Internet slang testifies to the functional dynamics of the modern Russian language, therefore it is of particular interest to linguists. The scientific novelty of the study lies in developing the word-formation and functional-semantic classifications of Russian Internet slang. The paper presents the analysis of 120 lexical units related to Internet slang. These units are considered in three aspects: meaning, word-formation types and intentions. As a result, it has been proved that Russian Internet slang as an ambivalent phenomenon, on the one hand, contributes to an increase in the expressiveness and emotionality of virtual communication and, on the other hand, it can negatively affect the literacy level of native speakers of the Russian language.
Comparative Study of Uniform and Graded Meshes for Solving Convection-Diffusion Equation with Quadratic Source
Authors:   Universiti Tun Hussein Onn Malaysia, Abdullah Aslam
Published: April 2023

Due to its fundamental nature, the problems of convection-diffusion are discussed in various aviation, science and engineering applications. Among major applications are in the study of the dynamics of aircraft wake vortex and its interaction with turbulent jet which is a very serious hazard in aviation. Other applications include those in the investigation of intrusive sampling of jet engine exhaust gases, and the effectiveness of hot fluid injection in the removal of ice on aircraft wings. The numerical solutions of convection-diffusion require propermeshing schemes. Among major meshes in computational fluid dynamics are those of uniform, piecewise-uniform, graded, and hybrid over which the solutions of discretized governing equations are found. Bad solutions as spurious fluctuations, over-or under-predictions, and excessive computation time might be the results of unwitting application of the meshes. Accentuating comparative effectiveness of two meshes, namely uniform mesh and graded mesh with mesh expansion factor, this paper takes the solution of aconvection-diffusion equation with quadratic source term into account. The problem is solved by assigning several values of mesh expansion factor to graded mesh, while mesh number is kept constant. The factors are calculated based on the generalization oftheir logarithmically linear relationship with low Peclet numbers derived in previous work. Based on the values of Peclet number, five test cases are considered. Graded mesh is proven relatively more robust, particularly due the solution on the mesh beingfree from spurious fluctuation. Furthermore, the accuracy level of the solution of up to two order of magnitude higher is obtained. The mesh expansion factor therefore contributes to a stable and highly accurate solution corresponding to all interested Peclet numbers.

Published: April 2023

Natural fibres nowadays have been famously investigated as alternative fibres due to the depletion of petroleum sources. There are several natural fibres such as jute, hemp, sisal, kenaf, and pineapple leaf that have been actively investigated in terms of their mechanical properties. Malaysia produces kenaf and pineapple as its main commodities. The sources of kenaf and pineapple leaf can be obtained easily. Therefore, this research is focusing on the kenaf and pineapple leaf. Previous researchers have proved that the kenaf and pineapple leaf fibres have good mechanical properties. This study aims to characterized the mechanical properties of a hybrid kenaf and pineapple leaf Fibre (PALF) epoxy composite for engineering application. Different compositions ofkenaf and PALF were formulated to compare the best composition in terms of maximum stress. The tensile test was performed via the Universal Testing Machine. Hybridization of pineapple leaf fibre and kenaf fibre at a composition of 75 % pineapple leaf fibre to 25% kenaf fibre which is 87.06 MPa, shows the highest maximum stress. The result found that this composition performs better than the previous investigation of hybrid natural fibre. As a result, the findings of this study may provide a clear indication that natural fibre should be used rather than being discarded, particularly by the agricultural industry.

Composite material offers excellent properties such as lightweight, high strength toweight ratios, and excellent corrosion resistance. Universiti Tun Hussein Onn Malaysia successfully developed a Cargo Drone (C-Drone) using aluminium alloy as its structure. The future enhancement is looking at the potential of composite material for C-Drone application. Therefore, this research aims to study the stress properties of aluminium alloy and glass fibre composite for C-Drone application via simulation analysis. The scope of this study focuses on the landing gear part of the C-Drone. The drawingof C-Drone was analysed through SolidWorks software to obtain the result of the material reacting to stress, strain, and displacement. The result shows that glass fibre with brittle properties can withstand a high amount of stress, acceptable strain rate,acceptable deformation and reduced weight up to 10% compared to aluminium alloy. This research proves that composite material such as glass fibre reinforced plastic can become an alternative to the current aluminium alloy 6061-T6.

Published: April 2023

The work-from-home scenario is a sudden drift in today's work environment. As the fear of the coronavirus grows, many industries have already pressed for this type of setup, even academic institutions. Merging work and personal life closer together and other challenges in working or teaching from home raise many questions about the faculty's well-being and performance. The main focus of this study was to determine the levels of workplace well-being and job performance in the new normal and to rule out a significant relationship between the two variables among the work-from-home faculty of Batangas State University. This study utilized a quantitative approach and used the descriptive correlational method design. Through stratified random sampling, the study's respondents were 140 WFH faculty. Pearson Product-Moment Correlation Coefficient was applied for the data analyzing method. The findings revealed that positive emotions were significantly related to task performance, contextual performance, and counter-productive work behavior. The engagement had a significant relationship with task performance and counter-productive work behavior but had no significant relationship with contextual performance. Moreover, relationships had a significant relationship with contextual performance and counter-productive work behavior but had no significant relationship with task performance. Meaning had a significant relationship with task performance and counter-productive work behavior but had no significant relationship with contextual performance. Finally, accomplishment had a significant relationship with task performance but had no significant relationship with contextual performance and counter-productive work behavior.

Published: April 2023

Due to the Covid-19 virus, everything has undergone a significant pivot, including livelihood, access to medicine, and the movement of products and services. One of the most affected industries is the hospitality and tourism sector. There was a sudden shift from the regular operation of a hotel to becoming a quarantine facility for isolated guests. Hence, this research explored the employees' experiences working in the COVID-19 quarantine hotel as the basis for developing a human resource crisis management framework. This study utilized basic qualitative research. The researchers used the interview as its tool. Informants of the study were three front desk clerks, one housekeeping staff, one maintenance staff and one supervisor. Consequently, this study revealed that the hotel changes are adjustments to how operations are carried out, how services are provided, and how many staff choose to stay despite the risk of contamination. In accordance with that, most employees experienced psychological and physical problems due to the increased risk of contamination from the virus and the fact that the employees were separated from their families. It is recommended that hotel management should be advised to conduct essential orientations on the nature of the hotel and health protocols and to offer proper familiarization about Covid-19 for awareness. Management should formulate laying of expectations on the roles and responsibilities of each employee.
Triple helix in the age of the fourth industrial revolution and the spatial pattern of Hungarian industry
Authors: KIss Eva , Varga György , Kuttor Dániel
Published: April 2023

The fourth industrial revolution is one of the most significant challenges of the past decade in Hungary as well. Its driving forces are Industry 4.0 technologies, which result in radical changes in all areas of life. This also affects the spheres of the triple helix (university-industry-government) and how they cooperate. Based on various databases and qualitative research, the main goal of the study is to explore these changes in the field of higher education in technical vocations. We will also examine how all this affects the geography of Hungarian industry. Analysing the description of the technical courses, we have identified a new course (mechatronics engineering) and a new form of training (dual training) as a response to the new technological challenges. German companies, which are at the forefront of the application of Industry 4.0 technologies, have not only encouraged the introduction of dual training, but also the cooperation between the spheres. This is evaluated from the perspective of a multi-site German company (Continental) and a university (the University of Miskolc) using the example of mechatronics engineering training to present the major characteristics of cooperation in connection with new technologies. The main result and novelty of the study is that it points out that the changes in the spheres of the triple helix and their cooperation, which were also motivated by the technological revolution, can also reshape the spatial structure of Hungarian industry.
Derzhavin’s Poem: “To Evgenii. Life at Zvanka”
Authors:   University of Leiden, Klein Joachim
Published: April 2023

This paper approaches Derzhavin’s poem To Evgenii. Life at Zvanka from three angles: 1. Its relation to Horace’s II epode Beatus ille…. 2. The contrasting backdrop which is established in the first stanzas of the poem: the imperial court of Saint-Petersburg. 3. A further backdrop of this kind, which is implicit in the poem: a contemporary disdain for gentry landowners. In the light of Peter I’s reforms, their lifestyle was perceived as a backward relic of medieval Russia. From this point of view, Derzhavin’s idealized picture of country life is not only a criticism of court life, but also a didactic attempt to bring the country gentry’s way of life into accord with contemporary Russian culture: Zvanka was supposed to serve as a model to emulate.
Case marking and definiteness in Slavic appositional constructions
Authors:   Institute for Linguistic Studies, Russian Academy of Sciences, Logvinova Natalia ,   National Research University Higher School of Economics
Published: April 2023

This paper is a corpus-based study of Slavic appositional constructions. Out of material taken from seven Slavic languages, two aspects of the morphosyntax of close appositions in Slavic are considered: case concord and definiteness marking. The first section of the paper considers the factors that affect case concord in appositions in Russian, Ukrainian, Belarusian, Czech, Polish, Croatian, and Slovenian. Based on the data of the corpora it is shown that in all seven languages, inherent plurality and frequency of proper names significantly affect the probability of concord being present. Moreover, it is shown that the likelihood of concord differs across cases, and almost all languages considered follow the case hierarchy GEN>DAT>LOC>INS. The second portion of the paper considers definiteness marking in Bulgarian and Macedonian appositional constructions. Based on the obtained data, it is argued that appositions with different lexemes can have different syntactic structures in these languages.
Francis Thomson and his “Clavis” to Ancient Slavic Translated Literature
Authors:   Institute of Russian Literature (Pushkin House), Russian Academy of Sciences, Bulanin Dmitrii
Published: April 2023

The article deals with the academic legacy of Francis Thomson (1935–2021), an outstanding connoisseur of Medieval Slavic literature, who especially distinguished himself in the study of the translated section of this literature. The article also discusses fundamental the prominent academic’s source studies and bibliographic studies, in the course of which he established and described the originals of hundreds and even thousands of translated texts that exist in Church Slavonic. These texts entered the bulk of literature accumulated by South and East Slavs in the period between the 9th and the first quarter of the 18th century. The discoveries of Francis Thomson are first of all reflected in his articles, of which more than one and a half hundred are published, and which are already highly appreciated in Slavistics. His discoveries are also fixed in his famous “cartotheca,” of which little was known, mainly from the words of its creator. This project was conceived first as a “clavis” to the repertoire of Slavic translated literature, but taking into account the rich information contained therein, we can state that it went far beyond its original purpose. The author of the handwritten “cartotheca” worked on it for fifty years, and, already during his lifetime, it turned into a kind of a legend among specialists. Currently, this opus magnum of the researcher is located at the Catholic University of Leuven (Louvain), where its net publication is being prepared. It can be said without exaggeration that further study of the translated literature of the medieval Slavs is unthinkable without taking into account the work of Francis Thomson.
Analabos: Origin, Evolution and Terminological Confusion
Authors:   Russian Christian Academy for the Humanities, Kurbanov Andrey , Spyridonova Lydia ,   Russian Christian Academy for the Humanities
Published: April 2023

In modern research, as well as in everyday practice, there is a general confusion about ‎the name and the shape of the analabos, one of the original elements of the‎ Byzantine monastic habit. Thus, slavists and archaeologists use this term as an equivalent of the paramand (which is different from the Byzantine paramand in shape and use); ‎byzantinists and art historians see it as an equivalent of the Latin scapular, that is, in fact, an extension of the Byzantine cowl, which we can always see in traditional representations of holy monks. The variety of names ‎and the interpretation of the terms for this attribute is far from clear. Information ‎about the analabos’ original shape can be obtained from early monastic texts, Byzantine literature, Old Russian literature, liturgical monuments, artistic representations of saints in illuminated manuscripts and finds from excavations of Russian monastic tombs. Our analysis reveals the characteristic forms and functions of the analabos at different times, both in the Greek world and in the Slavonic world, and also shows the reasons for the terminological confusion.
Graveyard Walk in the First Third of the 19th Century: Healthcare, Memorial Politics, Aesthetics, Literature
Authors:   Institute of Russian Literature (Pushkin House) of the Russian Academy of Sciences, Kardash Elena
Published: April 2023

The undertaken thorough historical and literary analysis of A. S. Pushkin’s poem “When lost in thought I wander beyond the town…” (“Kogda za gorodom zadumchiv ia brozhu…”, 1836) reveals its pretexts and likely sources among which the most important ones are G. G. Byron’s epigram “On Lord Elgin”, the 5th, 8th and 11th letters of A. Pichot’s “Voyage historique et littéraire en Angleterre et en Ecosse” and the 1st part of W. Wordsworth’s «Essay upon Epitaphs». Meanwhile, the article outlines a broader representative spectrum of sociocultural, psychological and aesthetical ideas which determine how the authors of the end of the 18th—the first third of the 19th century deal with funerary and memorial topics. The article shows how medical and healthcare attitudes of the epoch, as well as some ideological shifts, which paved the way for European cemetery reform, filter the choices and the ways of textual representations of traditional literary rhetorics (Horatian topos of beatus ille in particular). On the other hand, the study demonstrates how narrative models conventional for the first third of 19th century function as the universal language suitable for describing utterly different graveyard spaces. The important research subject is the authors’ critical attitude to the official state commemorative politics, which involved a major change in aesthetic trends of the epoch. Development of associanist perception and sentience theory constitutes new demands for funerary and commemorative material culture and, in the case of Pushkin’s poem, stimulates the rethinking and transformation of well-established elegiac figurative and narrative patterns.
Ótrodu ne vidano, sródu ne slykhano, a na rodú napisano. Features of the Development of Mobile Accent Type Nouns in Slavic Idioms
Authors:   Russian State University for the Humanities, Pekunova Irina
Published: April 2023

The article considers various types of accent curves among underived substantives belonging to the accentual paradigm c in South Slavic medieval manuscripts. Three main non-trivial evolutional types of historically end-stressed forms are observed: 1) the «anti-enclinomenal» type α with substitution of end stress with stem stress in phonetically disyllabic groups and preservation of end stress in other positions (GSg гла́вы — ѹ главы̀ — свободы̀); 2) the “new-enclinomenal” type β with conversion of historically end-stressed disyllabic word forms to enclinomena and preservation of the end-stressed forms of polysyllabic stems (NAPl срь́дца — на́ срьдца — тѣлеса̀) and 3) the type γ/δ with new penultimate stress in polysyllabic stems (слове́си) or even in any position (LSg плъ́ти — въ плъ́ти — слове́си — въ слове́си). Hereby the evolution of type β preserves the set of various accent contours of common-slavic a.p. c, although the accent curve itself may be modified. The evolutions of other types change not only the accent curve but also the set of accent contours represented in a.p. c paradigms.
“In the Union, Everyone Should Read”: Reader as an Institution of the Soviet Culture
Authors:   Lomonosov Moscow State University, Tsyganov Dmitry
Published: April 2023

The present review focuses on the third volume of the collective study Reading Russia: A History of Reading in Modern Russia and aims at analyzing the methods of studying reading practices proposed in the aforementioned publication. The articles included in the peer-reviewed volume are studied in detail against the background of previously published scholarly literature on the history of reading, as well as in relation to archival and previously (un)published materials that have so escaped researchers’ attention. The broad historical and literary material shows that the «narratives» proposed in the reviewed volume do not present a full-fledged history of reading practices, but describe only individual disparate reading strategies of typologically different readers. The forms of institutionalization of reading in the USSR that were left out are sometimes much more important in the context of transformations in reading practices than the total collection of the «cases» offered in the volume. At the same time, the case study review offers an opportunity to talk about ‘the reader of the 20th century’ as a special institution of Soviet culture. This is why much of the review presents an attempt to find other principles and strategies of analysis on which the history of reading in the «small twentieth century» can be based. The article offers a sociological portrait of the average reader, whose main features were formed during the Stalinist era and remained unchanged throughout the previous century. These features have existed in the same form for almost a quarter of the present century. The material that has been excluded from the present research can be divided into three groups: facts that characterize the Soviet state of affairs; information about the most important forms of institutionalized reading in the USSR-specific cultural environment; information concerning aesthetic and economic aspects of the book. A detailed commentary on each of these groups is intended to supplement and elaborate on the authors' concept. Along with the analysis of archival documents, we draw on materials from the funds of various public organizations and bodies, as well as periodicals, published memoirs, diaries and other materials available to us.
Andrei Aleksandrovich Teils, a Writer Who Nonetheless Existed
Authors:   Institute of Russian Literature (Pushkin House), Russian Academy of Sciences, Lappo-Danilevskii Konstantin
Published: April 2023

The paper reconstructs the biography of Andrei Aleksandrovich Teil’s (1782–1822), the author of “Hercules and Daianira”, a tragedy in аlexandrine verse (1807). He is attributed various sentimental poems and translations from French that were published in the journals “Ippokrena” (1799), “Litsei” (1806), “Novosti” (1799), “Novosti russkoi literatury” (1803), “Severnyi vestnik” (1805) and “Severnyi Merkurii” (1811). These publications were signed “A. de Teil’s”, “An. Teil’s”, “An: Teil’s”, “A. Teil’s”, “Teil’s” and until now have been erroneously considered to be the work of Anton Antonovich Teil’s (1733 — after 1798), the uncle of Andrei Aleksandrovich. It has not been noticed that at one point the author revealed his identity by putting the name “Andrei Teil’s” under a poetic translation from Voltaire in “Litsei” (1806). References made in “Puteshestvie v Norvegiiu odnogo molodogo cheloveka v 1801 godu” [A Young Man’s Journey to Norway in 1801] (published in “Severnyi Merkurii” [The Northern Mercury] in 1811; signed A. Teil’s) to the anonymous “Puteshestvie v Shvetsiiu” [A Journey to Sweden] (1811; published after the last part of “Puteshestvie v Norvegiiu odnogo molodogo cheloveka v 1801 godu” in the same journal) indicate clearly that both of these travelogues were written by Andrei Aleksandrovich Teil’s. Furthermore, the travel routes described therein coincide with two trips he took in 1800 and 1801, as can be seen in his curriculum vitae in the Russian State Naval Archive. Closely connected with these texts is the “Idilliia na vozvrashchenie iz Norvegii druga moego A. A. T..lsa v 800-m godu oktiabria 29 dnia” [Idyll on the Return from Norway of My Friend A. A. T..ls on 29 October 1800], published in 1810 in the same review and signed with the cryptonym “P - r U - - ov”. In this case, it is highly probable that the author was Petr Aleksandrovich Ushakov (1783 — after 1804), a classmate of Andrei Aleksandrovich Teil’s at the navy cadet school and a close relative of the famous writer Aleksandr Nikolaevich Radishchev (1749–1802).

Authors:   Department of Mechanical Engineering, National Institute of Technology Kurukshetra, Haryana, India, Panchal Dilbagh
Published: April 2023

The current work presents a two phase Intuitionistic Fuzzy (IF) based framework, for investigating the reliability analysis of a Turbine Unit (TU) in a sugar mill process industry. Intuitionistic Fuzzy Lambda Tau (IFLT) approach-based series-parallel expressions have been applied for computing various reliability indices. For series arrangement OR gate transitions expression has been used, and for parallel arrangement AND gate expressions has been used for calculation of reliability parameters for membership and non- membership function. For membership function, system’s availability decreases by 0.000002% for spread value ±15% to±30%, further decreases by 0.000005% for spread value ± 30% to±45%. While, non- membership function-based system’s availability decreases by 0.000003% for spread value ± 15% to±30% and further decreases by 0.000007 % for spread value ± 30% to±45%. The reliability trends at various spreads lay the foundation of studying the failure behaviour of the TU and to plan a maintenance schedule.

Role of the HTR2A gene in the development of type 2 diabetes
Authors: Gorbatovskaya K.S. , Larkina A.P. , Kochetova O.V. , Korytina G.F.
Published: April 2023

Type II diabetes mellitus (T2DM) of the second type is a chronic multifactorial disease that develops due to insulin resistance. Currently, more than 100 genes have been described that are associated with the risk of developing T2DM.Taking into account, that obesity is one of the factors predisposing to the development of type 2 diabetes, it seems appropriate to study the genes responsible for the formation of addictive behavior, in this case, eating behavior. The aim of the study was to analyze the association of polymorphic locus rs6313 of the HTR2A gene with T2DM and its complications in Tatars from Republic of Bashkortostan. The duration of T2DM was associated with the rs6313 locus of HTR2A gene; thus, among carriers of the AC and CC genotypes, the duration was 6.87 (0.53) years, while for carriers of the AA genotype only 4.79 (0.54) (P=0.018). There was an association with the risk of developing diabetic cataracts for carriers of the CC genotypers6313 locus of HTR2A gene, which accounted for 40%, while among patients without cataracts, the number of CC carriers was only 16.6% (OR = 3.36 95% CI 1.25-9.00, P = 0.02). The number of carriers of the AC and CC genotypes rs6313 locus of HTR2A gene among patients with polyneuropathies reached to 80.8% versus 61.8% among patients without this complication (OR = 2.60 95%CI 1.29-5.23, P = 0.005).

Published: April 2023

In this work, Yb2Si2O7 powder was synthesized from Yb2O3 and SiO2 powders and applied to aluminum substrates by atmospheric plasma spraying. Phase composition and microstructure were examined and density, porosity, and hardness were assessed. Thermal stability was evaluated by thermogravimetry and differential thermal analysis and thermal conductivity was measured. The as-sprayed coating was mainly composed of crystalline Yb2Si2O7 with a small amount of Yb2SiO5 and amorphous Yb2Si2O7. It had a dense structure containing pores, microcracks, and other types of defects. TG-DTA tests showed that there was almost no mass change from room temperature to 1200 °C, although a sharp exothermic peak appeared at 1038 °C, indicating that the amorphous phase had crystallized. The thermal conductivity of the coating decreased with increasing temperature, reaching a minimum of 0.68 W/(m·K) at 600 °C, followed by an increase at higher temperatures.

This study assesses the viability of three suspension spray processes for producing photocatalytic TiO2. In the experiments, flame, plasma, and HVOF torches were used to spray TiO2 suspensions onto stainless steel substrates, varying process parameters in order to gauge their effect on phase composition, crystal size and, in turn, photoactivity. The TiO2 samples were characterized by means of XRD, SEM, and UV-Vis analysis and photocatalytic hydrogen-production testing. Suspension flame spraying proved to be the most effective method, producing phase-controlled nanostructured titania 32% more photoactive than the SPS samples and up to five times more active than analogous coatings produced by CVD.

Published: April 2023

This study investigates the influence of particle size, nozzle diameter, gas flow rate, and stand-off distance on the microstructure and density of suspension plasma sprayed yttrium-oxide coatings and the intermediate effect of particle characteristics. Three ethanol suspensions were prepared, one with coarse Y2O3, one with fine Y2O3, and one with submicron YSZ. The suspensions were injected vertically into the plasma jet downstream of the nozzle and a thermal spray sensor was used to measure in-flight velocity and temperature. The coatings were found to have columnar and dense vertically cracked (DVC) microstructure, varying in hardness and density. Text results and examination findings are presented and correlated with spray parameters, particle properties, and possible coating formation mechanisms.

Published: April 2023

In this work, micro-plasma spraying is used to produce hydroxyapatite coatings on Ti-6Al-4V substrates. To understand coating formation mechanisms, in-flight particle velocity and surface temperature were monitored under different spraying conditions. XRD measurements show that the resulting coatings have a high degree of crystallinity with little amorphous or metastable phases. Some of the coatings were also found to have a uniformly distributed columnar structure, corresponding to a strong (002) texture and excellent stability in Hanks’ salt solution even after 14 days of immersion.

Published: April 2023

High-Sn bearing alloys have been used for more than a century in many areas of industry. They are typically applied by casting, although thermal spraying is gaining in use, particularly for component repairs. This study evaluates the effects of HVOF spray parameters on the velocity, temperature, size, and trajectory of Babbitt particles and correlates the in-flight characteristics with coating porosity and intermetallic phase distribution. In the experiments, Babbitt layers up to 370 μm thick were deposited on carbon steel substrates while measuring particle properties and deposition efficiency. Coating samples were analyzed by means of optical and electronic microscopy and some were chemically etched to reveal the size and distribution of intermetallic phases. Test results show a significant refinement in intermetallic phase distribution when compared with commercial flame and arc-sprayed coatings.

Published: April 2023

In this work, a design-of-experiments approach is used to map the main parameters of a high-velocity airfuel (HVAF) spraying process. Chromium carbide based material with a NiFeCrSi matrix was sprayed with varying gas flows and nozzle designs while monitoring their effect on particle temperature, velocity, and coating build-up. It was found that sufficient heating is critical to abrasive wear resistance and that particle temperatures are primarily controlled by fuel flow rates. Nozzle geometry, on the other hand, had the biggest effect on particle velocity, which was found to increase nearly 100 m/s by switching from a cylindrical to a convergent-divergent design.
Fluid Dynamics and Modelling of Plasma Jet in PS-PVD Process and Monte Carlo Simulations of PS-PVD Columns
Authors: Wang P. , Mücke R. , He W. , Mauer G. , Vaßen R.
Published: April 2023

A numerical model of a supersonic compressible plasma flow has been developed with the aid of CFD software to describe the thermodynamic and transport properties of a plasma jet in order to investigate the PS-PVD process and how to optimize it for thermal barrier coatings and, in particular, the formation of columnar microstructures. The required properties of the plasma gas mixtures were obtained as a function of temperature and pressure from thermodynamic calculations in chemical equilibrium with the effect of ionization. Two-dimensional Monte Carlo simulations were conducted to provide insight on the evolution of columnar microstructure, accounting for self-shadowing and vapor incidence angle but ignoring the effect of diffusion. Simulated structures and predicted values are presented and compared with actual images and measurements.

Published: April 2023

This study demonstrates a new approach for producing thick copper coatings on steel by cold spraying via nitrogen gas. To overcome delamination problems without resorting to helium, substrate surfaces are treated prior to deposition using a forced-pulse waterjet. Samples with different levels of roughness were prepared using both conventional and waterjet surface treatments. The samples were then coated with thick Cu using only N2 and adhesion tests were performed. Test results show good coating adhesion on all waterjet treated substrates with bond strengths ranging from approximately 25 MPa to 58 MPa, depending on surface roughness. Consistent with previous studies, cold spray Cu did not adhere to any substrates that had been polished or grit blasted. It is shown that the pulsed waterjet creates a surface with anchoring features that interlock with incoming particles to form a strong mechanical bond.

Published: April 2023

This study evaluates a new iron-based hardfacing powder alloy. The powder, a FeWCrCB tool steel, is applied to mild steel substrates by plasma transferred arc (PTA) and laser cladding. The clad specimens are examined and tested for weldability, impact and abrasive wear resistance, and wear life. It is shown that the alloy solidifies in a narrow temperature range, first forming a fcc phase followed by a eutectic structure consisting of austenite, carbides, and borides. After solidification, the austenite is transformed to martensite. Impact wear testing shows that the new alloy offers approximately ten times longer life than tungsten-based nickel-matrix composites, but it was outperformed by 50% in abrasive wear tests.

Published: April 2023

This study assesses the thermal stability of YSZ coatings produced from nanostructured feedstock by means of atmospheric and suspension plasma spraying. Free-standing YSZ coatings were isothermally treated for 24 h at different temperatures (1200-1600 °C) and at 1550 °C for 20 to 100 h. Afterwards, the coatings were examined to determine the effect of heating on phase composition, microstructure, morphology, and hardness. No evidence of tetragonal-monoclinic phase transformation was detected in the coatings that had been treated for 24 h, even at 1600 °C, but in coatings treated for different periods of time at 1550 °C, a phase transformation occurred after 40 h. Overall, the suspension plasma sprayed coating showed the greatest degree of change due to thermal aging.

Published: April 2023

Thermal barrier coatings (TBCs) consisting of a MCrAlY bond coat and a YSZ topcoat were air plasma sprayed onto Hastelloy X substrates. Samples were thermally cycled between 100 °C and 1100 °C and thermal fatigue failures were investigated via microstructure analyses. Final fatigue failure was caused by the formation of interface-parallel cracks in the topcoat, which was found to strongly related to the oxidation behavior of the bond coat. The development of oxide layers was therefore studied in detail and a thermo-kinetic model was used to explore the role of elemental diffusion in oxide formation.
