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.
Nickel plating is an integral part of the decorative chrome plating process and is applied prior to the chromium layer. The electrical charge applied to nickel plating baths may potentially result in emissions of nickel.he electrical charge during the chrome plating process causes the hexavalent chromium to be emitted from the bath as an aerosol that, once emitted from the facility, can be inhaled and entrained inside the lungs.
