FIELD: powder metallurgy.
SUBSTANCE: invention relates to powder metallurgy, in particular to powder materials for applying wear-resistant coatings by gas-thermal spraying on various parts of machines and equipment subjected to intense abrasive wear during their operation. The powder material for applying a wear-resistant gas-thermal coating, obtained by self-spreading high-temperature synthesis, consists of a mixture of nickel-based alloy powder containing chromium, boron, silicon, iron and carbon, and aluminum oxide powder, with the following component ratio, wt.%: aluminum oxide powder - 10, nickel-based alloy powder - 90.
EFFECT: invention is aimed at improving the structure of the applied layer, achieving high-temperature resistance and chemical stability of the powder material components, which affect the quality of the coating applied to the surface.
