Hexa and tri-valent chrome plating info


I'd like to learn more about hexavalent and trivalent chromium plating, is there any good book or paper on this topic?

Hexavalent chromium solutions are the conventional plating system which has been around for 90 years, and which started with the 100:1 chrome:sulfuric bath, and includes the fluoride catalyst and the newer proprietary etch-free catalyst baths. All trivalent chromium plating is from proprietary baths--available from such suppliers as Atotech, Enthone-OMI, and Macdermid. These baths are very different one from the other and the suppliers will explain what is involved in setting up and plating out from their trivalent plating baths. As of yet there are no trivalent hard chromium plating baths.
