摘要：
The electrochemical activity and the corrosion properties of five commercial lead anodes were examined by the conventional polarisation methods and the electrochemical impedance spectroscopy method. The results show that the anode Pb-0.62Ag alloy had a lower overpotential for anode reaction than the others. The corrosion resistance after polarisation of the anode Pb-0.62Ag alloy was higher than that of the Pb-0.29Ag-0.1Ca alloy, Pb-0.58Ag alloy and Pb-0.67Ag alloy, but lower than that of the anode Pb-0.72Ag alloy. However, the anode Pb-0.72Ag alloy had the highest overpotential. When anodes Pb-0.72Ag alloy and Pb-0.62Ag alloy were used, the cathode current efficiencies were higher, while anodes Pb-0.29Ag-0.1Ca alloy, Pb-0.58Ag alloy and Pb-0.67Ag alloy gave lower current efficiency. Regarding these several factors, the anode Pb-0.62Ag alloy is the best choice.
