Study of chromium plating anode with trivalent chromium

To compare the advantages and disadvantages of hexavalent chrolmium ion and trivalent chrolmium ion. The research progress and application situation of graphite anode, lead and lead base alloy anode, DSA anode in trivalent chromium chromium plating process in recent years is summarized. The fact that research and application of new type insoluble anode is one of effective methods which can solve the key problems such as plating solution stabilization, cathode product quality and tank voltage high in trivalent chromium chromium plating process is proposed. The fact that multi-element com- posite electrode material and functionally gradient composite electrode material produced through electrolytic deposition method is one of the main research directions in future is pointed out.
