FIELD: engineering industry, chemistry.
SUBSTANCE: gas turbine part consists of metal base made from superalloy, a lower bonding layer and external ceramic coating. Lower bonding layer is formed on the base, and includes intermetallic material containing aluminium, nickel and platinum. External ceramic coating is attached by aluminium oxide film formed on the lower bonding layer. The latter mainly consists of three-component Ni-Pt-Al system of α-NiPt-type structure with aluminium additives, and namely Ni-Pt-AI system of NizPtyAlx composition, where z, y, and x are chosen so that 0.05 < z < 0.40, 0.30 < y < 0.60, and 0.15 < x < 0.40. Forming method of thermal protective coating on metal base made from superalloy involves forming of lower bonding layer on the base and forming of external ceramic layer attached by aluminium oxide film formed on the lower bonding layer. The latter mainly consists of three-component Ni-Pt-Al system of α-NiPt-type structure with aluminium additives.
EFFECT: improving strength and resistance of ceramic material to delamination, as well as reducing mass and production cost of protective coating.
