    Fatigue Strength of Nitrided Steels in Corrosion-Active Media of the Food Enterprises
    (2019-07) Stechishin, M.S.; Skyba, M.E.; Sukhenko, Yu.G.; Tsepenyuk, M.I.
    We study the effects of the modes of nitriding in glow discharge on the low- and high-cycle fatigue of structural steels in acid, alkaline, and neutral model solutions and in air.

    Wear resistance and physicochemical properties of 12XH3A carbohydrated steel
    (Khmelnytskyi National University, 2020) Skyba, M.Ye.; Stechyshyn, M.S.; Luk’yanyuk, M.M.; Martynyuk, A.V.; Tsepenyuk, M.I.; Gerasimenko, V.A.
    The results of the study of anhydrous carbohydrogenation influence in a smoldering discharge on the microhardness of a hardened 12XH3A steel layer depending on the propane content and pressure of the gas environment are presented in the paper. In accordance with the developed methodology of studying the influence of technological parameters of the process of carbonylation on the properties of structural materials, optimal modes of hardening of 12XH3A steel, depending on the operating conditions have been found.

    Wear resistance of structural steels nitroded in cyclic-commuted discharge at limit modes of friction
    (Хмельницький національний університет, 2022) Stechyshyn, M.S.; Lyukhovets, V.V.; Stechyshyn, N.M.; Tsepenyuk, M.I.; Стечишин, М.С.; Люховець, В.В.; Стечишина, Н.М.; Лук’янюк, М.В.
    The article discusses the method of conducting tribological studies at the limit modes of friction of nitrided and non-nitrided steels 20 and 45 in order to achieve a comparison of the results of laboratory tests with operational data. The relationship of structural phases in time is significantly influenced by the initial state of the surface and its physical and mechanical characteristics, pressure on the contact surface, sliding speed, and all these parameters for the limit mode of friction are closely related.Carrying out tests on the wear resistance of samples made of different materials and with significantly different characteristics of the surface layer at the same parameters of the test regime is impossible in most cases, since the obtained results are problematic to compare.
