Abstrakt: The antifriction properties of coatings in the form of a nanocomposite of a silica layer with molybdenum disulfide nanoparticles distributed in it, whose average sizes are 70, 64, 61, and 53 nm and concentrations are 80, 73, 68, and 62 wt %, respectively, grown via plasma-chemical deposition at atmospheric pressure on a 12Cr18Ni10Ti steel, are studied. The best tribotechnical properties are established for a SiO2+ 68% MoS2coating (61 nm) which possesses the most stationary friction mode and a friction force two times lower as compared to a MoS2-free SiO2coating.
