FIELD: mechanical engineering.
SUBSTANCE: method comprises applying layers based on chrome and aluminum and heat treating of the layers. The chrome layer is applied by means of diffusion saturation in the circulating gas. The saturation component comprise, in mass per cents, 60-98 of chrome, 1-35 of alloy comprising 80 of nickel and 20 of yttrium, and 1-5 of nickel chloride.
EFFECT: enhanced durability.
