BRIGHT DIP FOR ELECTROPLATED CHROMIUM

摘要

This disclosure relates a bright dip for chromium electroplated from a solution containing chromium (III) thiocyanate complexes comprising a ferricyanide solution capable of forming complexes with chromium hydroxide species and of detaching the complexes once formed from the surface of an electroplated deposit without significant attack or etching of the deposit. The ferricyanide solution preferably comprises K3Fe(CN)6. The solution is preferably alkaline.
