Abstract

Diffusion coating of an internal surface of a workpiece accessible only a through very narrow passageway, is simply effected by coating that surface with a uniform layer of particles of the metal to be diffused into it, and then holding the thus- prepared workpiece at diffusion- coating temperature in a diffusion- coating atmosphere.
