Abstract
This invention relates to an improved method for electroplating a layer of nickel onto titanium base alloy substrates. It is particularly useful in electroplating a layer of nickel onto titanium alloys which contain refractory metal elements, such as the alloy Ti-8Al-1V-1Mo. The method includes the steps of etching the surface of the substrate with a solution containing hydrofluoric acid and hydrochloric acid, followed by electroplating the etched surface in a nickel sulfamate solution.
