Hardening of Ceramic Heat-protective Layers on Metallic Substances

We developed a technology of hardening heat-protective ZrO2-Y2O3 ceramic coatings. The method includes reinforcement of ceramics by ceramic fibers and reinforcement of metal substrates using nichrome spirals. The microstructure of the coating, strength characteristics and heat resistance were studied. Keywords: composite coatings, zirconium dioxide, yttrium oxide, ceramic fiber, metal substrates, heat resistance

International students academic mobility automatization in higher education establishments

The research is dedicated to the question of international studentsтacademic mobility automatization due to engineering and design of the special information system. This system should minimize the role of an expert at each stage of mobility support. Some features of such system are considered in the paper.В докладе рассматривается вопрос автоматизации международной студенческой академической мобильности за счёт разработки и внедрения информационной системы, минимизирующей участие эксперта в процессе сопровождения мобильности. Выдвинуты идеи относительно составных модулей такой системы

The influence of powders properties on the ceramic properties was investigated.Работа выполнена при финансовой поддержке Минобрнауки России, соглашение о предоставлении субсидии от 23.10.2017 г. № 14.581.21.0028 (уникальный идентификатор соглашения RFMEFI58117X0028), в рамках ФЦП “Исследования и разработки по приоритетным направлениям развития научно-технологического комплекса России на 2014–2020 годы”

PRODUCTION OF HIGH-POROUS CERAMIC MATERIALS BASED ON ALUMINUM OXIDE

In this work, we described the process of high- porous ceramic production by impregnating of polyurethane sponges with a slurry contained difference percentage of glass poweder. As a result, samples with high strength and porosity were obtained

DEVELOPMENT OF THE SOFTWARE FOR THE ANALYSIS AND CALCULATION OF TELERENTHENOGRAMM BY DOCTORS-ORTHODONTS

In the framework of this study, software was developed for the analysis and calculation of TRG. Software development was carried out jointly with the Ural State Medical University (UGMU), the Department of Children's Dentistry and Orthodontics. The software calculates the TRG by its own methods of UGMU, and also has the opportunity to create its own methods for calculating the TRG. In the software, it is planned to use the technology of machine learning (Neural networks). This will help make the process of calculating the TWG easier, since the points from the methodology will be placed automatically

THE SYNTHESIS OF CERAMIC ZrO2-Y2O3 FIBERS BY THE METHOD OF IMPREGNATION OF NONWOVEN VISCOSE MATERIAL

The possibility of synthesis of ZrO2 - Y2O3 ceramic fibers by means of impregnation of viscose material with solutions of zirconyl nitrate with the addition of yttrium nitrate and subsequent high - temperature roasting was considered. It was shown, that the efficiency of the formation of oxide fibers was largely determined by the concentration of the impregnating solution
