Popis:	We study the chemical and structural inhomogeneities and the parameters of wear resistance of the coatings obtained by the arc-welding method. The coatings were obtained from PR-KhN80SSR3, PN-AN-34, and Kh17N8S6G powders based on nickel, cobalt, and iron, respectively, and from an experimental powder based on Ni and Fe. The tribological properties of iron-based alloys are better than for the cobalt- and nickel-based alloys. In the course of friction, the austenitic component of the coating undergoes plastic deformation as a result of which it covers the surface as a lubricant, which decreases the friction coefficient and wear.
