Thermochemical Synthesis of Coatings of Tribotechnical Function Based on Molybdenum Diselenide MoSe2 on Construction Steels

We present the results on the influence of parameters of the thermochemical treatment process in selenium vapor during production of solid lubricant coatings from molybdenum diselenide on the construction steel specimens with a plasma Mo coating. We propose an empirical mathematical model of the temperature–time parameters of the Mo selenization process making it possible to control the quality of the resulting coatings depending on the requirements for their tribotechnical properties. Their tribotechnical characteristics in air and in vacuum are evaluated within the temperature range of 20–600°C.
