| Objective To study the electrochemical performances of three Al-Zn-In aluminum alloy sacrificial anodes with different compositions in conventional seawater environment. Methods Sacrificial Anodecurrent efficiency test and surface morphology observation were used. Results The current efficiency of three aluminum alloy sacrificial anodes with different components was all over 90%. The surface dissolution of aluminum alloy sacrificial anode of component 3 was the most uniform, showed uniform dissolution morphology with no obvious pitting and intergranular corrosion. Conclusion The electrochemical performance of Al-Zn-In sacrificial anode can be improved by adding adequate amount of In, Zn and moderate Si elements. Among three Al-Zn-In sacrificial anodes with different composition, the electrochemical performance of sacrificial anode with component 3 is the best. |
