FIELD: metallurgy.
SUBSTANCE: method includes applying a metal coating and applying an electric arc treatment to this coating. The electric arc treatment is performed on the pre-applied metal coating with formation of protective layer consisting exclusively of intermetallic compounds. After the electric arc treatment, additional thin metal coating is applied.
EFFECT: protection against oxidative corrosion and hydrogen effects, hardening surfaces of parts to improve their wear resistance.
