FIELD: gas-turbine engines.
SUBSTANCE: invention contains description of formation of oxidation resistant and abrasion resistant protective coating on treated part of component main body by means of electrode consisting of powder mix-formed body including powder resistant to metal oxidation and ceramic powder, or consisting of thermal treated formed, body, by means of impulse electric discharge between electrode and treated part of main body of component. As a result, electrode material provides settling, diffusion and/or welding of treated part of main body of component owing to energy of electric discharge.
EFFECT: increased abrasion resistance and oxidation resistance.
