Abstract: A chromium electroplating electrolyte containing trivalent chromium ions, a complexant, a buffer agent and thiocyanate ions for promoting chromium deposition, the thiocyanate having a molar concentration lower than that of the chromium ions. The chromium preferably has a concentration lower than 0.01M. Preferably the complexant is selected so that the stability constant K1 of chromium complex is in the range 10 M . Complexants in this range include aspartic acid, iminodiacetic acid, nitrilotriacetic acid and 5-sulphosalicylic acid.
