Abstract:
A method of coating a superalloy surface, said method comprising: (1) preparing a slurry comprising a metal coating powder and a carrier/adhesive resin that vaporizes leaving essentially no contaminating residue when heated to a temperature effective to diffuse the metal coating powder into the surface of a superalloy material; wherein said carrier/adhesive resin is a urethane oligomer/(meth) acrylate monomer blend that vaporizes leaving no contaminating residue when heated to a temperature of about 1250Â° F.; (2) depositing said slurry onto the surface of a superalloy material to form a coated surface; (3) curing the coated surface; and (4) heating said coated surface to a temperature and for a time effective to diffuse the coating into the surface.
