It has been difficult to electrolytically obtain crack- free chromium plating because of the high stresses caused by several factors. Accordingly, electroplating of nickel- chromium also encounters a similar problem. Cracks in chromium- containing plating was ascribed, in a certain sense, to the formation of a hydride formed through hydrogen adsorption from the electrolyte. A periodical pulse reverse plating current would enhance the release of hydrogen and hence the elimination of cracking. The present work describes a successful process for obtaining crack- free nickel- chromium plating and the effects of experimental variables on plating compositions.
