ABSTRACT:
The present invention is directed to a coating process for forming a high ality, high ductility, metallurgically bonded coating on a substrate or part. The process comprises applying a coating to the substrate using an HVOF spray coating technique and subjecting the coated substrate to a stepped heat treatment for diffusing the coating into the substrate while substantially avoiding the formation of macro cracks.
