ABSTRACT:
Methods for selectively applying a diffusion aluminide coating to the surface of a metal article while keeping other article surfaces free of the coating are described. The method includes the steps of injection molding a mixture of materials onto the surfaces which are to be kept free of coating; the material comprises solid particles effective in preventing deposition of the coating onto the surfaces and a moldable amorphous thermoplastic resin; it contains no volatilizable solvents. The mixture is applied to the article surface to a thickness of about 5 millimeters. It is useful in pack diffusion as well as vapor phase diffusion aluminide coating operations.
