The paper presents the results of metallographic and tribological studies of 40Kh steel and multi component coating (Ni-Cr-B-Si, Co-Cr-W-Ni-B-Si) with the addition of 5 and 10 vol.% nano-tungsten carbide powder to the charge. The regularities of changes in the friction coefficients from pressure, sliding speed, jamming load from sliding speed and wear intensity of steel and surfaced coatings are shown.
