The structural and phase condition, microhardness and wear resistance of nitrided high-chromium wire steels 40Kh13, 40Kh17M, 02Kh17N11M2 and gasothermal coatings from these steels sprayed with the use of a high-enthalpy combustible gas are compared in the initial condition and after ion-plasma nitriding at 740 K. The phase composition and the microhardness of the nitrided wire materials used for the spraying are studied. The nitriding is shown to have a positive effect on the wear resistance and structure of the gasothermal coatings.
