The purpose of the work is to create protective gas-thermal coatings from metal-ceramic powder materials (Ti, Cr)C-Ni with a high level of wear resistance for strengthening and restoring parts of aviation and ground machinery. Research methods – coatings were applied by plasma and detonation sputtering methods on UPU-3D and Dnipro-3M installations, respectively, the structural-phase composition of powders and coatings was studied using JEOL JAMP-950 and TESCAN VEGA3 electron microscopes; durometric analysis was performed on a micro-hardness tester PMT-3; adhesion was determined by the pin method, and porosity was determined by the incisal method; tribotechnical properties were determined under the conditions of sliding friction without lubrication according to the "shaft - bushing" scheme on the M-22M installation, and under the conditions of fretting corrosion on the МFC-2 installation; the oxidation process was carried out under isothermal conditions in the LHT 01/7 D furnace at temperatures of 600–1000 oС. The structure, fluidity and bulk weight of composite powders of the system (Ti, Cr)C-Ni were studied. Technological modes of sputtering of these powders were optimized and the structure of the obtained coatings was studied, their adhesion and porosity were determined. Tribotechnical tests of the obtained coatings were carried out under the conditions of sliding friction without lubrication and fretting corrosion, and their resistance to high-temperature oxidation at temperatures up to 1000 °C was investigated.
