Process for the electrophoretic deposition of metal powder for the recoating of a part by diffusion brazing, and electrophoresis bath for use therein

摘要

Metal powder for recoating a superalloy part by a diffusion brazing heat treatment is deposited on the part by electrophoresis in a bath comprising an aqueous solution of from 7.5 to 17.5 g/1 of a natural gum based binder and, in dispersion in the solution, from 1.75 to 2.25 kg/1 of a known mixture of two metal powders suitable for the recoating.
