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.
Plating is used to decorate objects, for corrosion inhibition, to improve solderability, to harden, to improve wearability, to reduce friction, to improve paint adhesion, to alter conductivity, to improve IR reflectivity, for radiation shielding, and for other purposes.he most common form of chrome plating is the thin, decorative bright chrome, which is typically a 10- Âµm layer over an underlying nickel plate. When plating on iron or steel, an underlying plating of copper allows the nickel to adhere.
