METHOD FOR REPAIR AND RESTORATION OF A CERAMIC THERMAL BARRIER-COATED SUBSTRATE BY PROVIDING AN INTERMETALLIC COATING

An aluminide coating is applied to a portion of the surface of an article that already has a thermal barrier coating system in place over another portion of its surface. The portion of the surface to be coated is contacted, at elevated temperature, with an aluminide coating source material that is a...

Zusammenfassung:	An aluminide coating is applied to a portion of the surface of an article that already has a thermal barrier coating system in place over another portion of its surface. The portion of the surface to be coated is contacted, at elevated temperature, with an aluminide coating source material that is a mixture of from about 18 to about 45 weight percent of a metallic source of aluminum and the balance ceramic particles. The metallic source of aluminum may be pure aluminum or an aluminum- containing alloy. No halide activator is present in the aluminide coating source material.
