Abstract

Ti-based oxide-coated anodes have been widely utilized in trivalent chromium solution, but few in hexavalent chromium plating process. In this paper, by means of Hull cell, electrochemical measurement, long term stability test, the performance of DSA (IrO₂, Ta₂O₅) and DSA (IrO₂, Pt) anode in hexavalent chromium process is studied in comparison with tin-lead alloy anode. The results show that DSA anode has larger active surface area, lower oxygen evolution potential and better electrocatalytic activity in chromium solution, especially DSA (IrO₂, Pt) anode has the best electrocatalytic activity at high current density region. However, due to the presence of F^- additives in plating bath the Ti- based coated anodes exhibit poorer stability and shorter lifetime compared to the lead-tin anode.
