ABSTRACT:
Complete coating or localized repair and replacement of a diffusion aluminide coating applied to the surface of an article is attained through use of a powdered Fe-Al alloy as a source of aluminum. In another aspect, more accurate control of a coating method, such as for aluminide diffusion coating, is achieved when a source powder is provided in a layer, such as a tape, preferably by combining the powder with a binder which decomposes substantially without residue upon heating.
