摘　　要：通过正交试验筛选确定了Al-Zn-In-Si牺牲阳极材料的最佳配比为Zn 5.5%,In 0.020%,Si 0.11%,Fe 0.12%。并对其电化学性能进行研究。结果表明,Al-5.5Zn-0.02In-0.11Si牺牲阳极材料的电化学性能指标包括开路电位、工作电位、实际电化学容量、电流效率、表面溶解形貌等,均达到或超过国家标准。The electrochemical performance of 9 types of Al-Zn-In-Si sacrificial anode materials with different amounts of Zn, In, Si and Fe were studied in natural seawater. The test results showed that the electrochemical performance of Al-Zn-In-Si meets and exceeds the national standard. The composition of Al-Zn-In-Si anode was optimized through orthogonal test. The optimum contents of alloy elements were as follows.. Zn 5.5 % In 0. 020% Si 0. 11%; Fe 0. 12%.
