The presented research considers the tribological properties of titanium carbide coatings TiC and their areas of application. It is noted that titanium carbide TiC is one of the most effective materials used as a wear resistant coating. TiC to the greatest extent satisfies the requirements for coatings: good adhesion to the surface of the material the base; corrosion resistance, low tendency to seizure and cold bonding. Arc plating vacuum deposition (cathodic arc ion plating) Arc-PVD is widely used to apply high-quality titanium-based coatings. The article considers the issues of wear resistance of carbidetitanium coatings obtained by the Arc-PVD method with respect to friction at high pressures with lubrication. The Arc-PVD method makes it possible to widely vary the structure of the emerging coatings due to the change in pressure in the working chamber and the potential applied to the sublayer. The article shows the results of comparative tests of samples on a friction machine according to the scheme of two rotating rollers. It is shown that at different loading levels (50 and 500 H) the wear resistance of coated samples significantly exceeds the wear resistance of hardened steel samples. On the basis of experimental studies, the technological modes of Arc-PVD are proposed for the formation of coatings with optimal durability.
