Component, anti-oxidation coating for such a component and method of producing the same

摘要

A component such as a gas turbine engine component has an oxidation protective layer formed as a substrate surface region in a substrate of the component. The substrate has a nickel-based composition including nickel and an aluminum proportion of greater than 4.5 weight %. The surface region is formed by diffusion of at least platinum into the substrate surface region to provide an integrated platinum proportion of 5 to 40 weight percent over the integration depth range in the surface region.
