Abstract
A method of improving oxidation resistance of a platinum modified aluminide diffusion coating on a substrate involves electroplating the substrate with a platinum layer from an aqueous hydroxide based electroplating solution and aluminizing the substrate to grow the platinum modified aluminide diffusion coating on said layer. The electroplating solution preferably includes an alkali element and/or alkaline earth element that is incorporated in the platinum layer and in the aluminide diffusion coating formed thereon to significantly improve oxidation resistance of the coating.
