FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy, and namely to nickel-based alloys of protective coatings of parts of a gas turbine. Nickel-based alloy for the protective coating of gas turbine parts contains the following, wt %: cobalt 24-26, chrome 16-25, aluminium 9-12, yttrium 0.1-0.7 and/or at least one metal of the group containing scandium and rare-earth elements, non-obligatorily, phosphorus 0.1-0.7, non-obligatorily, silicon 0.1-0.6; it does not contain rhenium; nickel is the rest.
EFFECT: protective layer has high corrosion and oxidation resistance at high temperature.
