Plasma Sprayed Coating – Substrate Interface Study
Authors: Písacka J. , Laub D. , Buffat F. 
Published: May 2022

Abstract
This paper examines an aluminum oxide coating plasma-sprayed onto a substrate made of high-quality stainless steel by means of light microscopy, X-ray diffractometry, and scanning and transmission electron microscopy (TEM). The aim is to determine the phases that form preferentially at the transition. It is observed that high amount of corundum phase was found in a plasma sprayed white alumina coating. XRD phase analysis of the coating indicated that all three major alumina phases were present: alpha-, gamma-, and delta-aluminum oxide. Further development in the field of TEM sample preparation is required in order to obtain larger electron-permeable surfaces, since it is not clear whether the alpha-aluminum oxide found at the transition is in the form of a spatter or a grain introduced by sandblasting.

Influence of Substrate Deformation on Formation of Splats During Thermal Spraying
Authors: Sobolev V.V. , Guilemany J.M. 
Published: May 2022

Abstract
Due to high kinetic energy of an impinging droplet a strong elastic deformation of the substrate and the formation of its curvature occur which influence the dynamics of the droplet flattening (particularly the thickness and the diameter of a splat) and a pressure formed upon the droplet impact. This paper involves investigation of these phenomena and the development of the simple analytical formulae needed by the engineering practice which enables to estimate the influence of the substrate deformation on the droplet flattening and the high pressure generation. The analytical results are obtained with regard to the variation of the splash properties and the pressure that arises when the droplet is flattened during thermal spraying. The splash curvature caused by the drop impact is taken into account. The paper also analyzes the role of surface effects. The results obtained show good agreement with the experimental observations.

Manufacturing and Experimental Evaluation of Combined Ceramic Polymer Coating Systems for Tribological Application
Authors: Scherer D. , Gadow R. , Killinger A. 
Published: May 2022

Abstract
This paper aims to fabricate wear resistant composite coatings on light metal substrates which also exhibit low friction coefficients. It demonstrates that combined ceramic polymer coating systems are a powerful concept for industrial applications where high wear resistance, creep resistance and compressive strength as well as low friction coefficients are required. The results show that, under the specific experimental conditions used, the titanium dioxide layer in connection with the applied lubricant lacquer showed better performance than the mixed aluminum oxide/titanium dioxide layers.

The Optimization of Plasma Sprayed Ni-50%Cr Coatings by Orthogonal Experimental Design
Authors: Li C.-J. , Li F.-H. , Sonoya K. 
Published: May 2022

Abstract
In this paper, the influence of the plasma spray parameters on the mechanical properties of Ni-50% Cr coatings is systematically studied using the method of orthogonal regression test planning. The target properties include adhesive strength, micro-hardness, grinding wear, and erosion wear. The three spray parameters used as variables are plasma arc current, Ar flow rate, and spray distance. From the regression formulas, it is concluded that the effects of the spray parameters on the properties largely depend on the individual properties. Paper includes a German-language abstract.
Laser Shock Processing of Al-SiC Composite Coatings
Authors: Schnick T. , Hofmann U. , Steinhäuser S. , Wielage B. , Tondu S. , Peyre P. , Bartnicki E. , Pawlowski L. 
Published: May 2022

Abstract
Laser shock processing (LSP) is a surface treatment similar to shot peening, in which the compressive stresses in the material are created by laser-induced mechanical impacts. The tensions are of sufficient intensity to modify the microstructure and properties. In this paper, the laser pulses are generated with a power density of 5 to 8 GW/centimetres square with a neodymium laser. The glass laser is used to treat Al+SiC composite coatings, which were initially applied using the high-speed oxygen fuel spray technique. The laser-processed samples are prepared metallographically and examined for their microstructure with a scanning electron microscope. The latter is also used to investigate the surface morphology of laser-treated samples. Finally, the microhardness and the vibration wear resistance of the coatings are tested and compared with the data obtained for the samples in the sprayed state.

Changes in Properties of Detonation Sprayed Coatings as a Function of Temperature
Authors: Babul T. 
Published: May 2022

Abstract
This article presents one of the most advanced technologies for the application of powder coatings, the detonation spray method. The devices for measuring the temperature and the velocities of the powder particles are presented and the results obtained are shown. The article deals with results from wear tests as well as from fatigue strength tests. The tests are carried out on the coatings of the Ni-Cr-B-Si type applied to C45 steel. In addition, X-ray examinations, linear distribution of the chemical elements, microhardness measurements and metallographic examinations are carried out. The coating properties of the detonation-sprayed layers are compared with the same coatings, which were applied by means of plasma or flame spraying. Paper includes a German-language abstract.
Numerical Results of Off-Angle Thermal Spray Particle Impact
Authors: Bussmann M. , Chandra S. , Mostaghimi J. 
Published: May 2022

Abstract
This paper presents results regarding the influence of the spray angle on the spray shape. Simulations of the liquid dynamics of the impact of Ni particles, which were the characteristic of both HVOF and DC plasma conditions, are carried out. The results show that the splashes stretch with decreasing spray angle and confirm previous experimental observations to the effect that the splash area varies little with the spray angle. In addition, the results indicate that more than 90% of the material is applied "behind" the point of impact, even at spray angle is equal to 45 degree. Paper includes a German-language abstract.
Investigations of Thermal Barrier Coatings with Loading and Unloading to Various Stress Levels
Authors: Lin C.K. , Senturk U. , Lima R. , Berndt C.C. , Shieh J.C. , Lee P.Y. 
Published: May 2022

Abstract
In this paper, plasma sprayed thermal barrier coatings (TBCs) with and without bond coat are stressed to various stress levels under four point bending with in situ acoustic emission (AE) to monitor any cracking activities. Micro- and macro-cracks occurring during the tests are investigated to better understand the failure mechanisms of TBCs. The results show that limited AE activities were detected in the first four stress-relief cycles, while plastic deformation and the greatest AE activity were observed when the applied load exceeded the yield point. In addition, they show that a TBC system that contained an adhesive layer had less AE activity (cracking events) than the TBC without an adhesive layer. In addition, the samples tested at a main speed of 5 micrometer/s resulted in a higher AE activity than the samples tested at 10 micrometer/s. With increasing plastic deformation, macro cracks and surface cracks also occurred. Paper includes a German-language abstract.
Processing and Mechanical Properties of Plasma Sprayed Thermal Barrier Coatings
Authors: Senturk U. , Lima R.S. , Berndt C.C. , Lin C.K. , Lima C.R.C. 
Published: May 2022

Abstract
In this paper, the mechanical properties and cracking features of yttria stabilized zirconia with and without bond coat on steel substrates is investigated. Four point bending tests have been used to evaluate the mechanical properties, while acoustic emission (AE) has been used to in situ monitor the cracking behavior during the bend tests. In the sprayed state, the samples were characterized by four-point bending tests with local noise emission. In comparison with the substrate, the coated samples showed an increased flow pressure. It is also shown that the processing parameters, the cooling, and the adhesive layer have a significant influence on the flow pressure. It is proven that the cooling affects the behavior of the load-displacement curves. The AE analysis shows the different deformation behavior of the coating-substrate system for the different processing conditions. This is supported by the surface crack analysis. Paper includes a German-language abstract.
The Stiffness of Plasma Sprayed Zirconia Top Coats in TBCS
Authors: Thompson J.A. , Clyne T.W. 
Published: May 2022

Abstract
Thermal barrier coatings systems are composed of a zirconium dioxide-(6 to 8 wt.%) yttrium oxide ceramic top coat about 300-500 micrometer in thickness, deposited either by air plasma spraying or electron beam assisted physical vapour deposition, over an MCrAlY (M = Ni, Co or NiCo) bond coat, about 100 micrometer thick, deposited by vacuum plasma spraying. In this paper, the stiffness of as-sprayed zirconia is measured using three different techniques, namely cantilever beam bending, ultrasonic resonance and nanoindentation. The paper explores the effect of post-deposition heat treatment on the value obtained. The results show that the cantilever bend technique, employed with a high precision scanning laser method of displacement measurement, was found to be the most reliable procedure.

Conversion of Silanes Into SiC by RF Plasma Technology
Authors: Bouyer E. , Müller M. , Schiller G. , Henne R. 
Published: May 2022

Abstract
This paper reports on the synthesis of SiC material through the decomposition of silanes in a thermal high frequency (HF) plasma. The process is based on thermal plasma technology for chemical deposition from the gas phase and on suspension plasma spray technology, in which a liquid or suspension is injected axially and atomized in the plasma flame. The liquid silane then decomposes, and forms SiC with some gaseous by-products such as HCl. Various plasma parameters were varied, for example the plasma power level, the plasma gas composition, the chamber pressure, and the silane composition. The paper also presents first investigations into the elementary and phase composition as well as the morphology of the powders and coatings. Paper includes a German-language abstract.
Komponenten- und Verfahrensentwicklung beim DLR für das DC- und das HF-Plasmaspritzen (Components and process development of DC- and RF-plasma spraying at the German aerospace center DLR)
Authors: Borck V. , Schneider G. , Henne R. , Schiller G. , Fischer M. 
Published: May 2022

Abstract
More than 20 years the Institute of Technical Thermodynamics of the German Aerospace Center (DLR) in Stuttgart has been active in the field of plasma spray technology with improvements of spray equipment and their application. At the beginning the DC vacuum plasma spray method was in the center of interest and knowledge gained from rocket technology helped to develop supersonic nozzles for the plasma spray torches producing plasma jets with increased velocity and improved laminarity in order to get denser coatings with higher quality. In the meantime also nozzles for subsonic conditions with controlled expansion of the plasma jet leading to considerably increased deposition efficiency were developed as compatible parts for already existing equipment and made available on the market. In the next step also the DC plasma torches themselves have been improved. Recently a modern equipment for RF plasma technology could be developed and installed, where some new ideas could be realised. Paper text in German.
Two banks of the same river. Thomas Mann and his publishers Samuel Fischer and Gottfried Bermann Fischer
Authors: Kleeberg V. V. 
Published: May 2022

The enduring collaboration between the outstanding German writer and Nobel Prize winner Thomas Mann and the Frankfurt-based publishing house S. Fischer Verlag started in the late 19th c., with the publication of Mann’s early novella Little Herr Friedemann [Der kleine Herr Friedemann]. The year 1897 marked the start of Mann’s correspondence with Samuel Fischer and then his successor Gottfried Bermann Fischer, which spanned more than fifty years; the committed publisher saw to the publication of such landmarks of 20th-c. German literature as Buddenbrooks [Buddenbrooks — Verfall einer Familie], The Magic Mountain [Der Zauberberg], Lotte in Weimar , the four installments of Joseph and His Brothers [Joseph und seine Brüder], Doctor Faustus [Doktor Faustus], and Felix Krull [Bekenntnisse des Hochstaplers Felix Krull]. The novels appeared in print even during the author’s enforced emigration at the time of Nazi persecution. Resulting from this collaboration with the publisher, which exemplifies preservation and propagation of German literature’s humanistic traditions, was the fact that, upon Mann’s death, none of his completed works ended up locked up in his desk — all having been published.
Russia invaded by Germans A story of a literary sensation
Authors: Abdullaev E. V. 
Published: May 2022

The article is concerned with the literary history behind the anonymous brochure entitled La Russie Envahie par les Allemands, which appeared at the Leipzig Book Fair in 1844 and quickly became a sensation in Russia and Europe alike. Its author, a former member of the Arzamas Society Filipp Vigel (Weigel), had fallen under the spell of the Slavophiles. The brochure served as the first manifesto and the first attempt at a historical-philosophical justification of the anti-German sentiment espoused by the majority of the Russian elite during the reign of Nicholas I. The book’s publication is examined in the context of the rivalry between the Ministry of the Interior (where Vigel held an office from 1829 to 1840) and the Third Department, believed to be a stronghold of the German party, and the rising Pan-Slavism in Europe, whose principal champions were in correspondence with Vigel. In addition, the article considers the connection between the brochure’s fragment describing Pushkin’s death and the anonymous anti-German letters received by V. Zhukovsky and Count A. Orlov upon the poet’s tragic demise.

ВИДИ ЗАВДАНЬ АДМІНІСТРАТИВНО-ПРАВОВОГО РЕГУЛЮВАННЯ ВІДНОСИН У СФЕРІ ЕЛЕКТРОЕНЕРГЕТИКИ В УМОВАХ ЄВРОІНТЕГРАЦІЇ УКРАЇНИ
Authors: Mykolaiets D. 
Published: May 2022

Актуальність статті полягають в тому, що завдання адміністративно-правового регулювання відносин у сфері електроенергетики виступають критеріями ефективності та систематизованості адміністративного законодавства. Зі свого боку, дослідження адміністративного законодавства надасть можливість зрозуміти, які із завдань уже реалізуються, а які потребують впровадження для досягнення мети з осучаснення та підтримання сталого розвитку усієї сфери електроенергетики. Встановлення переліку завдань адміністративно-правового регулювання дозволить визначити довготривалі плани та стратегії, більш якісно проводити реформування, разом із розумінням сутності існуючих, на сьогодні, проблем у відносинах в сфері електроенергії. У статті проаналізовано види завдань адміністративно-правового регулювання відносин у сфері електроенергетики в умовах євроінтеграції України. Надано їх авторську класифікацію, що сформована на основі аналізу наукових підходів вчених вітчизняної правової доктрини. Охарактеризовано особливі риси кожного із видів. Наголошено, що адміністративно-правове регулювання ціноутворення в сфері електроенергетики повинно відбуватися лише частково щодо обмеження надмірно високих цін, адже лише за умов вільного ринку можливо буде оновити технології та надалі покращувати якість постачання електричної енергії. З’ясовано, що завдання адміністративно-правового регулювання відносин у сфері електроенергетики можливо розподілити на загальні та спеціальні. Різниця між ними полягає у поширеності, адже загальні завдання є властивими для регулювання відносин з використання паливно-енергетичних ресурсів, тоді як спеціальні можуть бути реалізовані виключно у відносинах в сфері електроенергетики. Зроблено висновок, що значна частина завдань, які стоять перед адміністративно-правовим регулюванням відносин у сфері електроенергетики ще потребує втілення. Реалізація таких завдань залежить, як від рівня юридичної техніки в нормативно-правових актах, так їх ефективності в сучасних національних умовах. Об’єднують усі завдання європейські тенденції розвитку відносин у сфері електроенергетики, які обов’язково мають бути відображені в законодавчих актах.
