FIELD: metallurgy.
SUBSTANCE: metal coating of nickel-based alloy for gas turbine parts contains γ and γ' phase and, optionally, β phase. Note here that said alloy contains the following substances, in wt %: tantalum - 0.1-7.0, cobalt - at least 1, chromium - 12-22, preferably, 15-19, aluminium - 5-15, preferably, 8-12. Note also that this alloy does not, preferably, contain silicon (Si) and/or hafnium (Hf) and/or zirconium.
EFFECT: high thermomechanical properties, resistance to oxidation, longer life.
