Abstract
A coated article has a metallic substrate with a substrate composition, and a metallic coating overlying and contacting the metallic substrate. The metallic coating has a metallic-coating composition different from the substrate composition. A protective coating overlies and contacts the metallic coating. The protective coating includes an aluminide layer overlying and contacting the metallic coating, and optionally a thermal barrier coating overlying and contacting the aluminide layer. This structure may be used to restore a key dimension of an article that has previously been in service and to protect the article as well.
