Decorative chrome plating on a motorcycle. Chrome plating (less commonly chromium plating), often referred to simply as chrome, is a technique of electroplating a thin layer of chromium onto a metal or plastic object.The chromed layer can be decorative, provide corrosion resistance, ease cleaning procedures, or increase surface hardness. typical hexavalent chromium plating process is: (1) activation bath, (2) chromium bath, (3) rinse, and (4) rinse. The activation bath is typically a tank of chromic acid with a reverse current run through it.
Hard-Chrome Plating. Hard-chrome plating is normally described as the application of an electroplated chrome deposit with a thickness of greater than 0.0002 inch. Hard-chrome deposits are normally plated to a thickness of 0.0005â0.01 inch, although in theory almost unlimited thicknesses can be achieved.LICK IMAGE TO ENLARGE (+). In decorative applications the chrome is plated as a thin (0.25â0.8 Î¼m) layer over nickel to provide an economical and highly corrosion resistant deposit. Fluoride-catalyzed processes are used with sulfate.
