New advanced and productive plasma sources equipped with electromagnetic filters have been developed to increase the deposition rate and obtain coatings with a low content of macroparticles. Combined plasma technology for functional, protective nanostructured coatings has been developed and implemented, and the following coatings have been obtained: MoN, TiAlCrN, TiAlCrCN, B4C, TaO, TaN, NbC, NbCN) for parts and assemblies of machines operating in harsh modes. The multicomponent coatings TiAlCrN and TiAlCrCN (analog of the tactical coating Black Cat Vergason Tech USA) were obtained by the method of vacuum-arc deposition with a modified source and a curvilinear filter. Tribological tests of coatings in the conditions of dry friction according to the "disk-pad" scheme are carried out. It was found that the Vickers microhardness varied from 26 to 41 GPa depending on the deposition parameters. The technology of nitriding of steel in plasma of non-independent gas discharge for strengthening of the surfaces working at high temperatures is developed. High values of surface hardness are due to the formation of a nitride layer consisting of both nitrides of the parent metal and nitrides of alloying elements. Nitriding increases the surface microhardness of AISI 430 steel from 213 to 1097 HV (approximately 5 times). A method for strengthening the surface of low- and high-carbon steel products with B4C coating applied by the ion-plasma method using a high-frequency plasma source with an applied external magnetic field is proposed. Tribological tests of boron carbide coating with a thickness of 0.5 μm and 3.0 μm on substrates of 12X17 and X12 steels were performed. The technology of deposition of tantalum nitride and oxide coatings, which were obtained by spraying a tantalum target with argon ions in the vacuum chamber of the Bulat installation Product Description popup.authors Garkusha Igor E.
