| Abstract: |
| Electrochemical analysis of Pb-Ca-Sn alloy anode after 360 hours copper electrowinning were studied by linear potential sweep method (LSV), cyclic voltammetry (CV) and Tafel curves, and the anode corrosion rate of the alloy was determined by weight loss method. The results show that corrosion resistance of Pb-Ca-Sn alloy anode is improved along with the increase of tin content. |
