Method of preparing nickel alloy parts for plating

摘要

A plating preparation method in which a nickel part is placed in an electrolyte bath of such acid concentration and such temperature as to promote thorough etching of the part surface and in which an etched part is allowed to soak in the same electrolyte bath for a period of time sufficient to dissolve formed metallic oxides. A coating of a base material is applied to the part following removal from the etching bath, the base material achieving a close intimate contact with the part surface and penetrating and interlocking with recessed areas of such surface.
