Abstract

Subject of research: technology for applying alloyed diamond-like coating (DLC), the influence of the atmosphere of the working area on the results of work. Purpose of research: search for the optimal alloyed diamond-like coating for loaded parts of a car transmission in order to ensure the required service life of the unit. Methods of research: all coatings, the research results of which are described in this article, were obtained by reactive magnetron sputtering. Main results of research: an analysis of the structural-phase state of a number of coatings is provided: containing chromium, titanium and silicon, obtained by magnetron sputtering in argon-acetylene-nitrogen atmospheres. Data are presented on the phase composition and size of coherent scattering regions, as well as the relationship between the structure and mechanical properties of the APP. A basic scheme for tribological testing of coatings has been determined, and the obtained nanocomposite structures of the APP are analyzed.
