    (Хмельницький національний університет, 2022) Fialko, N.M.; Shchepetov, V.V.; Kharchenko, S.D.; Kovtun, S.I.; Hladkyi, Ya.N.; Bys, S.S.; Фіалко, Н.М.; Щепетов, В.В; Харченко, С.Д.; Ковтун, І.І.; Г ладкий, Я.М.; Бись, С.С.
    The results of the study of glass-composite nanostructured self-lubricating coatings are presented. The structural components of these coatings significantly affect the graphitization process and provide an antifriction surface layer of α-graphite. The formation of this layer makes it possible to significantly minimize the contact parameters in the friction region. A significant effect of aluminoborosilicate in the form of a glass phase on the tribological properties of coatings is noted. An increase in adhesive strength is achieved by forming a surface layer of glassy sodium silicate. The presence of near-surface particles in the graphite layer does not affect the tribotechnical characteristics of the coatings. The developed glass-composite nanostructured self- lubricating coatings have high antifriction characteristics throughout the entire load- speed range.

    Self-lubricating glass composite magnesium carbide nanocoating
    (Хмельницький національний університет, 2025) Shchepetov, V.V.; Fialko, N.M.; Bys, S.S.
    The results of the study of the friction and wear characteristics of the developed nanostructured glass composite self-lubricating coatings are presented, the structural components which through magnesium carbide have a qualitative effect on the graphitization process due to the formation of a surface layer of carbide α-graphite, which, when combined with surface oxides characterized by low shear resistance, performs the role of solid lubricants under friction conditions. The positive role of the glass phase in the form of aluminoborosilicate, which affects the tribotechnical properties of coatings, has been established. It has been determined that the increase in adhesion strength is achieved by forming a surface layer of vitreous sodium silicate during spraying. It has been found that the intercalation of the graphite layer with dispersed particles of the surface structure does not significantly affect the tribotechnical characteristics. The developed nanostructured glass composite coatings showed high antifriction characteristics.
