The first commercial trivalent chromium bath, based on a sulfate/ chloride electrolyte, was introduced by Albright & Wilson in 1975. Since then, the long-term corrosion protection of trivalent chromium over multilayer nickel deposits has been proven repeatedly. Tests conducted by ASTM have shown that trivalent chromium deposits perform better than standard hexavalent chromium deposits, better than microcracked hexavalent chromium deposits and as good as microporous hexavalent chromium deposits. And the field performance of trivalent chromium has ...
