ABSTRACT:
A high temperature corrosion resistant nickel-base alloy, e.g. for turbine stator blades in gas turbine engines, providing a good balance between mechanical strength, oxidation resistance and compatibility between a coating and a substrate. A preferred composition of the coating alloy, which composition also provides a good balance between sulphidation and oxidation corrosion, is: aluminum 25-30%; chromium 3-14%; tantalum 7-9; yttrium 0.01-0.5%; nickel remainder. An article may be provided in which the coating is combined with a substrate of the same composition except in that the substrate has an aluminum content of 5-6%.
