Chromium Electroplating or people just say chrome plating is a process of metal coated using chromium substance or chromic acid. Why use chromium substance to cover metal surface? Chromium is a metal substance that resistant to corrosive while other metal like steel are easily to corrode affected by wet air. Chromium can’t be deposited from solution only chromic acid (CrO3) and water. There must be present in bath one or more acid radicals which act catalyst to bring about or aid in the cathodic deposition of chromium. The purity of chromic acid used is often not specified or established and yet the nature. The end of the process chrome will coated the surface of metal.
