ABSTRACT:
A method for applying a metallic coating to inner wall surfaces of a fluid-cooled turbomachinery blading member employs a substantially dry coating powder mixture which includes inert filler powder having a nonuniform powder size blend and a coating powder source which reacts with a halide activator to generate a coating vapor. The coating powder mixture is retained within a portion of the blading member during heating to generate the vapor. Blading members can be repaired and fluid-cooling passage exit openings can be resized.
