FIELD: metallurgy, namely chemical and heat treatment of refractory alloys, possibly used for applying protective coatings onto blades of gas-turbine engines.
SUBSTANCE: method comprises steps of applying onto inner and outer surfaces of parts diffusion aluminide coating in circulating gaseous medium; applying coating in low-active system at relation of reaction surfaces Fн/Fo = 0.3 - 0.7, where Fн - total surface of parts to be coated; Fo - total surface of saturating mixture; then applying onto outer surfaces of parts cladding coating, namely MeCrAlY, where Me - Ni, Co, NiCo by ion-plasma process or electron beam evaporation in vacuum.
EFFECT: improved fire and corrosion resistance of coating, increased resource of blades of gas-turbine engine.
