Abstract:

Due to the excellent corrosion and wear resistant properties of chromium deposits, researches to deposit chromium coatings of high quality from environmentally more acceptable Cr (III) electrolytes, in order to replace the highly toxic chromium (VI) processes currently employed have been made. The effects of composition and operating conditions on deposits quality and current efficiencies were investigated in a trivalent chromium plating process containing chromium alum, sodium citrate and sodium thiocyanate.
