In this work, a ZnO hemisphere-like structure co-doped with Er and Cr was obtained by the co-precipitation method for photocatalytic applications. The dopant’s effect on the ZnO lattice was investigated using X-ray diffraction, Raman, photoluminescence, UV-Vis and scanning electron microscopy/energy dispersive spectroscopy techniques. The photocatalytic response of the material was analyzed using methylene blue (MB) as the model pollutant under UV irradiation. The wurtzite structure of the Zn0.94Er0.02Cr0.04O compound presented distortions in the lattice due to the difference between the ionic radii of the Cr3+, Er3+ and Zn2+ cations. Oxygen vacancy defects were predominant, and the energy competition of the dopants interfered in the band gap energy of the material. In the photocatalytic test, the MB degradation rate was 42.3%. However, using optimized H2O2 concentration, the dye removal capacity reached 90.1%. Inhibitor tests showed that •OH radicals were the main species involved in MB degradation that occurred without the formation of toxic intermediates, as demonstrated in the ecotoxicity assays in Artemia salina. In short, the co-doping with Er and Cr proved to be an efficient strategy to obtain new materials for environmental remediation.
Higher-Order Multiplicative Derivative Iterative Scheme to Solve the Nonlinear Problems
Authors: Singh Gurjeet , Bhalla Sonia , Behl Ramandeep
Published: February 2023

Grossman and Katz (five decades ago) suggested a new definition of differential and integral calculus which utilizes the multiplicative and division operator as compared to addition and subtraction. Multiplicative calculus is a vital part of applied mathematics because of its application in the areas of biology, science and finance, biomedical, economic, etc. Therefore, we used a multiplicative calculus approach to develop a new fourth-order iterative scheme for multiple roots based on the well-known King’s method. In addition, we also propose a detailed convergence analysis of our scheme with the help of a multiplicative calculus approach rather than the normal one. Different kinds of numerical comparisons have been suggested and analyzed. The obtained results (from line graphs, bar graphs and tables) are very impressive compared to the earlier iterative methods of the same order with the ordinary derivative. Finally, the convergence of our technique is also analyzed by the basin of attractions, which also supports the theoretical aspects.

Authors: Dumitru Cătălin Constantin , Hostiuc Sorin , Vrapciu Alexandra Diana , Rusu Mugurel Constantin
Published: February 2023

Background and Objectives. The occipital artery (OA) is a posterior branch of the external carotid artery (ECA). The origin of the OA is commonly referred to a single landmark. We hypothesized that the origin of the OA could be variable as referred to the hyoid bone and the gonial angle. We thus aimed at patterning the vertical topographic possibilities of the OA origin. Materials and Methods. One hundred archived computed tomography angiograms were randomly selected, inclusion and exclusion criteria were applied, and 90 files were kept (53 males, 37 females). The cases were documented bilaterally for different levels of origin of the OA origin: type 1—infrahyoid; type 2—hyoid; 3—infragonial; 4—gonial; 5—supragonial; 6—origin from the internal carotid artery (ICA). Results. The incidence of unilateral types in the 180 OAs was: type 1—1.11%, type 2—5.56%, type 3—40.56%, type 4—28.33%, type 5—23.33% and type 6, ICA origin of the OA—1.11%. There was found a significant association between the location of the left and right origins of the OAs (Pearson Chi2 = 59.18, p < 0.001), which suggests the presence of a strong symmetry of the origins. Bilateral symmetry of the vertical types of the OA origin was observed in 56.67% of cases; in 43.33% there was bilateral asymmetry. Conclusions. The ICA origin of the OA is an extremely rare variant. For surgical planning or prior to endovascular approaches the topography of the OA origin should be carefully documented, as it may be located from an infrahyoid to a supragonial level.
Designing to Leverage Presence in VR Rhythm Games
Authors: Dongas Robert , Grace Kazjon
Published: February 2023

Rhythm games are known for their engaging gameplay and have gained renewed popularity with the adoption of virtual reality (VR) technology. While VR rhythm games have achieved commercial success, there is a lack of research on how and why they are engaging, and the connection between that engagement and immersion or presence. This study aims to understand how the design of two popular VR rhythm games, Beat Saber and Ragnarock, leverages presence to immerse players. Through a mixed-methods approach, utilising the Multimodal Presence Scale and a thematic analysis of open-ended questions, we discovered four mentalities which characterise user experiences: action, game, story and musical. We discuss how these mentalities can mediate presence and immersion, suggesting considerations for how designers can leverage this mapping for similar or related games.
Stability of Slow Magnetoacoustic and Entropy Waves in the Solar Coronal Plasma with Thermal Misbalance
Authors: Kolotkov Dmitrii Y. , Nakariakov Valery M. , Fihosy Joseph B.
Published: February 2023

The back-reaction of the perturbed thermal equilibrium in the solar corona on compressive perturbations, also known as the effect of wave-induced thermal misbalance, is known to result in thermal instabilities chiefly responsible for the formation of fine thermal structuring of the corona. We study the role of the magnetic field and field-aligned thermal conduction in triggering instabilities of slow magnetoacoustic and entropy waves in quiescent and hot active region loops, caused by thermal misbalance. Effects of the magnetic field are accounted for by including it in the parametrization of a guessed coronal heating function, and the finite plasma parameter β, in terms of the first-order thin flux tube approximation. Thermal conduction tends to stabilize both slow and entropy modes, broadening the interval of plausible coronal heating functions allowing for the existence of a thermodynamically stable corona. This effect is most pronounced for hot loops. In contrast to entropy waves, the stability of which is found to be insensitive to the possible dependence of the coronal heating function on the magnetic field, slow waves remain stable only for certain functional forms of this dependence, opening up perspectives for its seismological diagnostics in future.
Automated Battery Making Fault Classification Using Over-Sampled Image Data CNN Features
Authors: Din Nasir Ud , Zhang Li , Yang Yatao
Published: February 2023

Due to the tremendous expectations placed on batteries to produce a reliable and secure product, fault detection has become a critical part of the manufacturing process. Manually, it takes much labor and effort to test each battery individually for manufacturing faults including burning, welding that is too high, missing welds, shifting, welding holes, and so forth. Additionally, manual battery fault detection takes too much time and is extremely expensive. We solved this issue by using image processing and machine learning techniques to automatically detect faults in the battery manufacturing process. Our approach will reduce the need for human intervention, save time, and be easy to implement. A CMOS camera was used to collect a large number of images belonging to eight common battery manufacturing faults. The welding area of the batteries’ positive and negative terminals was captured from different distances, between 40 and 50 cm. Before deploying the learning models, first, we used the CNN for feature extraction from the image data. To over-sample the dataset, we used the Synthetic Minority Over-sampling Technique (SMOTE) since the dataset was highly imbalanced, resulting in over-fitting of the learning model. Several machine learning and deep learning models were deployed on the CNN-extracted features and over-sampled data. Random forest achieved a significant 84% accuracy with our proposed approach. Additionally, we applied K-fold cross-validation with the proposed approach to validate the significance of the approach, and the logistic regression achieved an 81.897% mean accuracy score and a +/− 0.0255 standard deviation.
Renewable Energy Communities in Positive Energy Districts: A Governance and Realisation Framework in Compliance with the Italian Regulation
Authors: Trevisan Riccardo , Ghiani Emilio , Pilo Fabrizio
Published: February 2023

Renewable energy communities, first outlined in the European Directives and recently transposed into the Italian regulatory framework, are introduced as innovative entities capable of fostering cooperation between active and passive users involved in the production, sharing, and use of locally produced energy according to innovative management schemes. Renewable energy communities empower the end-customers. Citizens and legal entities are committed to a rational and economical use of energy to achieve the community’s climate neutrality goals and pursue the ecological and energy transition objectives defined in the national recovery and resilience plan. In the future, a significant number of energy communities different actors participating from the residential, industrial, commercial, and tertiary sectors are expected to develop within city districts or in suburban settings. This paper proposes and develops a methodology capable of bridging the complexity that can characterise the prototyping, implementation, and management of an energy community within a positive energy district. The approach presented here can also be extended to other application contexts in urban or rural settings. Requirements and best practices for administrative, technical, and technological management have been identified to achieve this goal. Italy is one of the first states to embed in its regulatory framework the European Directives regarding renewable energy communities. These will have a significant impact on network management models and will provide new ways for creating social inclusion that may help achieve climate sustainability goals. A governance model has been formalised for the empowerment of energy community members, outlining a framework useful for planning the proper implementation of a renewable energy community according to current Italian regulations.

Published: February 2023

The stratum and microenvironment temperatures in a greenhouse are important factors that affect crop yield. In order to solve the problem of temperature imbalance caused by solar radiation in greenhouses, this paper proposes the application of a solar radiation array tube in a greenhouse. By adding water or phase change materials to the array tube, the influence of the array tube on the formation and microenvironment temperature changes was studied, and a 10-day test was carried out. A test group and control group were set up to monitor test results, and the ground was divided into six areas. The depths of each area were 10 cm, 30 cm, and 50 cm, and the heights of the greenhouse centers were 0 cm, 30 cm, 60 cm, 90 cm, 120 cm, 150 cm, and 180 cm. Via an analysis of the test results obtained for the formation and microenvironment temperature, the arrangement of the array tube was found to exert a constant temperature regulation effect on the microenvironment of the greenhouse at a formation depth of 10 cm and was able to improve this formation depth to a certain extent. The temperature at 30 cm and 50 cm plays a positive role in building a good vegetation growth environment.

Sabores y aromas del Litoral: la producción de conocimiento para la vitivinicultura local, Entre Ríos (1912-1930)
Authors: Priscila Cian Janet
Published: February 2023

La vitivinicultura en la provincia de Entre Ríos suscita la atención contemporánea de diversos sectores, como resultado del aumento de emprendimientos con fines productivos y de turismo rural asociado a la actividad. Este resurgimiento estimula la exploración sobre los antecedentes históricos del cultivo en la región, aspectos que requieren ser investigados desde diversas perspectivas. En este artículo realizamos una reconstrucción de los proyectos e instituciones desarrollados entre fines del siglo XIX y primera década del XX para mejorar la vitivinicultura local, centrándose en el caso de la Estación Enológica de Concordia. Sostenemos que su organización se produjo en un período en el que se apuntaba al fortalecimiento de la producción de vinos con características que se asemeja a lo que, actualmente, se conoce como terroir, iniciativa que era alentada por algunos técnicos del Ministerio de Agricultura Nacional (MAN). Dificultades económicas propias de la coyuntura, la expansión de otro tipo de cultivos en la provincia, cambios en la producción vitivinícola nacional y en la política educativa del MAN colaboraron en la reorientación que experimentó la institución.
Tras la práctica estatal: instituciones, proyectos y expertos durante la reconversión del agro en el Chaco (1976-1981)
Authors: Almirón Adrián
Published: February 2023

Las políticas agrarias aplicadas en la provincia del Chaco entre 1976 y 1981 cambiaron la estructura del campo con la aceleración del proceso de titularización de la tierra, la expansión de la frontera agropecuaria y la inserción de cultivos oleaginosos. Esta ruptura en el campo chaqueño fue propiciada por el gobierno para modernizar el agro, enfatizando la mecanización, el uso de semillas y la difusión de las nuevas formas de cultivo por parte de las instituciones técnicas y de investigación especializadas del agro, así como la diversificación productiva.

De esta forma, en el artículo reconstruimos las principales instituciones que se enfocaron en desarrollar estrategias para promover los cambios en el agro chaqueño. En particular, se analizan los trabajos realizados por las secretarías de Asuntos Agropecuarios, la Dirección de Extensión y el Instituto de Colonización y el Instituto Nacional de Tecnología Agropecuaria.  Para la elaboración del artículo examinamos los informes y las resoluciones emanadas de cada una de estas entidades públicas, de diversa jurisdicción, y la prensa local.
El humor político como herramienta antiperonista
Authors: Blanco Jessica
Published: February 2023

La intención de este artículo es analizar la columna humorística “Cartas a mi ñaña” durante el gobierno militar de 1943-1946, considerando algunos tópicos como la representación de los gobiernos, las formas de hacer política, la concepción de los partidos políticos y del pueblo, la relación de los sectores populares con lo político y el rol de los sindicatos. La hipótesis que guía el trabajo es que estos temas fueron modificándose al calor de la coyuntura política, y específicamente la preelectoral de 1946, en la que su creador Miguel Hynes O´Connor se presentaba como candidato a legislador. Asimismo, que bajo la matriz interpretativa civilización-barbarie y desde el humor político un sector autodenominado progresista y pro democrático contribuyó a cimentar imágenes despectivas de la relación entre la política y los sectores populares que perduran hasta el presente. “Cartas” se abordará a manera de prisma para observar el tópico peronismo-antiperonismo y las tensiones que este tándem encerraba desde ciertos ideales políticos liberales permeados por clivajes de clase.
Estéticas dominantes de la modernidad-colonialidad en la práctica y enseñanza de la arquitectura. El caso de Quito-Ecuador
Authors: Toro Mayorga Lorena , Prado Mateus Salvador
Published: February 2023

Desde la producción de formas arquitectónicas se pueden entender las características de las sociedades y viceversa, de ambos lados se dan posicionamientos, ajustes y transformaciones. Si bien la arquitectura ecuatoriana a finales del siglo XX se abre a una diversidad de registro e investigación, poco se ha reflexionado sobre preferencias estéticas. Este trabajo sostiene que la emergencia y persistencia de estéticas dominantes e identificadas con la modernidad en la arquitectura ecuatoriana preceden al apogeo del movimiento moderno del siglo XX; se trata de un proceso de larga data, profundamente anclado a una matriz colonial. Así lo evidencia la práctica arquitectónica vinculada al ideal de una modernidad situada en el Norte Global que muestra el predominio de la modernidad como aspiración permanente. Estas prácticas recaen más tarde en una enseñanza fuertemente vinculada a referentes externos que de otro lado han subordinado el conocimiento, re-conocimiento y registro de otras modernidades periférico-localizadas. Metodológicamente este trabajo tiene un alcance exploratorio-descriptivo con análisis heurístico desde una fase de investigación bibliográfica seguida por una fase de entrevistas. Los hallazgos se discuten como temas emergentes a la luz de los aportes teóricos del pensamiento decolonial latinoamericano para contribuir a miradas histórico-interdisciplinarias en la arquitectura.

Published: February 2023

Wood, acting as a construction material, has been utilized by humans since the beginning of times. The early human-made machines were made entirely from wood. With time, technical progress gradually displaced wood from machine design and construction. However, despite the passage of time, due to the low cost and availability of wood, the elements in the quickly worn out machine parts still were made from wood. Sliding bearing shells or replaceable gear teeth need to be replaced here. These elements can still be found in pre-war mills. This article contains examples overview of wood application in such areas as bearings, and discusses their advantages and disadvantages. It also indicates the desirability of undertaking further research on the use of wood in tribological pairs.

Published: February 2023

A exodontia do terceiro molar inferior pode causar uma lesão ao nervo alveolar inferior, quando sua raiz está próxima ou em contato com o canal da mandíbula (CM). Dentre os exames por imagem, a Tomografia Computadorizada por Feixe Cônico (TCFC) tem sido utilizada para definir esta relação. Objetivo: Avaliar relação de proximidade dos terceiros molares inferiores com o CM e associá-la ao tipo de impacção dentária utilizando a TCFC. Material e método: Foram avaliados 198 terceiros molares inferiores em TCFC, observando sua posição de acordo com a classificação de George-Winter e Pell-Gregory e a relação das raízes com o CM. Foi feita associação entre as variáveis observadas (Qui-quadrado) e o risco relativo (RR) e o IC95% foram estimados para associação entre variáveis. Resultados: De acordo com a classificação de George-Winter 112 dentes (56,6%) apresentaram impacção mesioangular, 47(23,7%) horizontal e 32(16,2%) vertical. Pela classificação de Pell Gregory 62(31,3%) estavam em posição 1B, 40(20,2%) em 2B, 31(15,7%) em 1A. Vinte e dois dentes (11,1%) estavam em proximidade com o CM, 176(88,9%) estavam em contato, sendo que 65(36,9%) destes estavam com as raízes por vestibular em relação ao CM. Não houve associação entre o tipo de impacção e sua relação com o CM (>0,05), entretanto, observou-se associação entre o contato das raízes com CM quando estão posicionadas por vestibular em relação a este (p≤0,05). Conclusão: A impacção dentária mais comum foi a mesioangular, posição 1B, havendo maior contato das raízes com a cortical vestibular do CM. A TCFC mostrou-se útil para esta avaliação.

Per l’edizione del Corbaccio: preliminari allo studio della tradizione
Authors: Giglio Lorenzo
Published: February 2023

The paper examines some critical aspects of the manuscript tradition of Boccaccio’s Corbaccio, starting from the results of the very few studies on the subject. Besides proposing an updated list of all the 79 available manuscripts that hand down the work, whose yet we don’t have any critical edition, he then demonstrates, through a number of examples, the benefits of widening perspective to the codes of the non-α family, but also of a comprehensive reconsideration of the status of α itself. In the absence of a solid classification of the whole manuscript tradition, the “traditional” hypothesis that the α2 group (and in particular the Mannelli codex) represents an advanced redaction of Boccaccio’s «umile trattato» risks to be too conditioning if assumed at such a preliminary stage.
«Venerabilem preceptorem meum Boccaccium de Certaldo»: i rapporti (intertestuali) fra Giovanni Boccaccio erudito e Benvenuto da Imola

Published: February 2023

The text of the commentary to the Georgics of Benvenuto da Imola allows to illuminate the intertextual relationships between Benvenuto da Imola and Giovanni Boccaccio. Through a series of examples that highlight clear dependence on the Genealogia Deorum Gentilium, the De montibus and the Zibaldone membranaceo, the aim is to show Benvenuto's intellectual and cultural debt to the preceptor Boccaccio, thus configuring the Imolese as a personally known disciple and one of the first readers of Boccaccio's Latin erudite works.
Osservazioni tassiane a margine dell’opera di Boccaccio
Authors: Incandela Marika
Published: February 2023

The essay proposes a study of the relationship between Tasso and Boccaccio, analysing the references to the ancient auctoritas present in Tasso's theoretical production. The sixteenth-century poet's interest in Boccaccio's works can be found in the author's epistolary, in the letters in which Tasso claims to be in possession of some of his texts or in those in which he explicitly requests them. As with Dante and Petrarch, the reading is careful and inclined to take the ancient source as a model for observations of a rhetorical, linguistic-grammatical and metrical nature. These observations form a non-systematic corpus of reflections on poetic language, an authentic reflection of an intimate dialogue between the author and Boccaccio.

A partir da etnografia com crianças realizamos uma escuta amorosa e comprometida com o que as crianças tinham a nos dizer a respeito das brincadeiras, dos brinquedos e das interações que experenciam nesses territórios crianceiros. Também, as narrativas das crianças e de duas pesquisadoras quilombolas, compõem o texto etnográfico. Por fim, o estudo anuncia as comunidades quilombolas do Itamoari e do Bairro Alto a partir do olhar das crianças, das expectativas em relação ao que seja ser criança e viver a infância nesses territórios amazônicos. Com a licença das crianças, ao adentramos em seus universos, ganha contorno no estudo, um território crianceiro revelador das culturas da infância quilombola.

ظهرت رُدود فعل مختلفة بين المجموعات الفكريّة والسياسيّة والحضاريّة ، وقد ظهرت هذه الردود في الأدب الإيراني خاصّة الشعر، جرّاء الحرب العالميّة الأولى ، ومن بين الشعراء الذين برزوا في هذا العصر السيّد أحمد بن شهاب ¬الدين الرَّضَوي الملقّب بالأديب البِيشاوَري الأكثر اعتناءًا بهذه الحرب . سوف نتناول في هذا البحث موضوع الحرب العالميّة الأولى في أشعار الأديب البِيشاوَري العربيّة وآراءه حول هذه الحرب وتداعياتها في إيران خاصّة ، والشرق والعالم الإسلامي عُمومًا . وقد توصّلت هذه الدراسة إلي نتائج ، أهمّها : علي الرغم من احتلال إيران بواسطة العُثمانيّين المتّحدين مع الألمان ؛ لكنّ الأديب البِيشاوَري لم يذكر ذلك الأمر في أشعاره واكتفى بذكر الاعتداء علي إيران بواسطة الدولتَين الروسيّة والبريطانيّة ، وذلك لانحيازه للألمان في تلك المدة . ويرسم الأديب البِيشاوَري الأوضاع المضطربة في إيران أيّام الحرب العالميّة الأولى في القصيدة التي لعن فيها الآخوند الخراساني وكأنه قصد أن يقول بأنّه لولا حماية الآخوند الخراساني للثورة الدستوريّة لم تصل إيران إلى تلك الحالة المضطربة .W

نسبت عدة أشعار إلى فاطمة الزهراء () في المصادر العربية. جمع بعض الباحثين هذه الأشعار في ديوان مستقل لكنهّم لم يراعوا الدّقة الكافية في جمع هذه الأشعار ونسبوا إليها () كلّ ما ذكرتها المصادر المختلفة، فهذه الدواوين لم تسلم من آفة الإفراط والتسامح. من جهة أخري أنكر بعض العلماء إنشادها() الشعر دون الاعتماد علي المعايير العلمية؛ فلذلك يهدف هذا المقال دراسة صحّة نسبة هذه الأشعار بوصفها نماذج رائعة من الشعر الإسلامي بطريقة منهجية؛ لأنّ المعصومين () عُرفوا بالفصاحة وقدرة البيان ولا تستثني فاطمة الزهراء () عن هذه. يعتمد المقال في هذا السبيل علي معيار الأسلوب في ضوء معادلة إحصائية مسماة بكيوسام. فإنّ هذه المعادلة تعتمد على تقييم ظاهرتين لغويتين ومقارنتهما، وهما طول الجمل وكلمات كثيرة التردّد في النص المدروس. تدلّ المعطيات الناتجة عن إجراء هذه المعادلة في الخطبة الفدكية والأشعار المنسوبة إليها () علي أنّه ليس توافق تامّ بين الأسلوبين كما ليس تنافر شديد بينهما؛ فهذه المسألة تمنع عن قبول نسبة كلّ هذه الأشعار إليها () وكما تمنع عن رفض نسبة كلّها وتشير إلي اختلاط أشعارها () بأشعار الآخرين وتؤكد علي أنّ بعض الأشعار المنسوبة إليها() للآخرين ولكنّها نُسبت إلى فاطمة () خطأ لأنّها () نطقت و استشهدت بها
دراسة مقارنة لتسجيل المعاملات العقارية في الشريعة الإسلامية والحقوق الإيرانية

في قانون التسجيل الإيراني، لا يعترف المشرع بنقل الملكية في المعاملات غير المنقولة دون تسجيل رسمي، في الواقع، في نظام التسجيل القانوني الإيراني، سعى المشرع إلى أن تكون الوثيقة العادية في نقل الممتلكات غير المنقولة غير ذات صلة وغير موثوقة. وتعتبر المعاملات في الممتلكات غير المنقولة مراسمية. ومع ذلك، بعد تعديل قانون التسجيل، تم تعديل قوانين في إيران انحرفت عن الغرض الأصلي لقانون التسجيل، وهو الطبيعة الرسمية للعقود غير المنقولة. مع تخصيص معظم قوانين التسجيل وكذلك مع سن قوانين جديدة، عاد إلى نظامه الإسلامي واعتبر معاملاتدغير منقولة بمثابة رضا. في الشريعة الإسلامية، وفقًا لآيات القرآن وروايات الأئمة، فإن وجوب تسجيل المعاملات من وجهة نظر الشريعة الإسلامية وعدم تسجيلها لا يبطل الفعل الشرعي بل أساسه هو الهداية للاقتراب من العدالة.. لذلك لا يمكن القول إن تسجيل المعاملات في الإسلام واجب ، لكن تسجيل المعاملات فيه طريقة إرشادية لمنع الأضرار المحتملة في المستقبل. تسعى هذه المقال، بمنهج وصفي - تحليلي وباستخدام قوانين إيران وآيات القرآن الكريم وأحاديث الأئمة والسنة النبوية، إلى دراسة مقارنة لتسجيل المعاملات غير المنقولة في الشريعة الإسلامية و النظان القانونية الايرانية.

Evaluation of structure and properties of boride coating with combined method of boron-copper plating of 45 steel

The complex diffusion saturation of the surface of steels with boron and metal by the solid-phase method can improve the functional properties of parts and tools. Thus, the combined process of simultaneous saturation with boron and copper (boron-copper plating) with the use of an exothermic reduction reaction of their oxides in the process of thermal chemical-treatment (TCT) provides a greater layer thickness compared to pure boron plating and makes it possible to increase the plasticity of the coating. The aim of the work was to evaluate the effect of the time of saturation with boron and copper on the structure and mechanical properties, including the fragility (plasticity) of the diffusion layer during the processing of 1045 steel. The boron-copper plating process was carried out at 1123 K for 3, 4 and 5 hours. As a result, diffusion layers with a thickness of 60, 160, and 180 µm were obtained with an uneven distribution of microhardness along the length of the coating. The microhardness of the surface layer is no more than 15 GPa. The maximum value of microhardness reaching HV 20 GPa after 4 and 5 hours of treatment is determined at a distance of up to 15...20 µm from the treated surface of the samples and with a length of up to 20...25 µm. Then the microhardness decreases monotonically and at the end of the layer has the values 17...18 GPa. The diffusion coefficient for the combined method of boron-copper plating was (6.8...7.1)•10–13 m2 /s, the optimal time for TCT was set at 4—5 hours. The results of a study to determine the fragility of diffusion layers showed that the plasticity of layers based on boron and copper is up to 2 times higher compared to pure boriding. Elemental analysis showed a high con centration of boron (22 % wt.) and copper (more than 2 % wt.) in the surface layer of the diffusion coating, which can confirm the formation of an iron-copper alloy on the surface of the treated sample and indicate the presence of a high concentration of higher boride on the surface. Then, a decrease in the boron concentration from the surface to the interface is observed, which indicates the formation of a lower boride. An increased concentration of carbon under the boron-copper layer is determined due to the displacement of carbon from the surface deep into the base, enhanced by the copper-containing component.
