<p>A high temperature resistant nickel-based or cobalt-based super-alloy component is provided with a gallium-based oxidation protective coating. An Independent claim is also included for producing an oxidation protective coating for a high temperature resistant nickel based or cobalt based super-alloy component, especially a gas turbine blade, by applying gallium onto the component. Prior to applying the gallium, the component is coated with a protective alloy of MCrAlY type, where M = Ni, Co or Fe, and Y = yttrium and/or one of Sc, La and Ce.</p> |
