摘　　要：综述了合金元素对AZ系列镁合金牺牲阳极材料的电流效率研究进展。对该系列镁合金内元素的作用进行分析,同时分析了常见添加元素对合金材料电流效率的影响机理。合金元素促使镁合金形成固溶体或使晶粒细化,从而抑制了材料的腐蚀速率,使其呈均匀腐蚀,结果显示提高了镁合金牺牲阳极材料的耐蚀性能及电流效率。该研究对镁合金牺牲阳极的设计提供了一定的技术参考。The current efficiency of alloy elements on AZ series magnesium alloy sacrificial anode materials is reviewed in this work.The effect of the elements in the magnesium alloy is analyzed,and the influence of common added elements on the current efficiency of alloy materials is analyzed.The alloy element causes the magnesium alloy to form a solid solution or refines the grain,thus suppressing the corrosion rate of the material and making it evenly corroded,which improves the corrosion resistance and current efficiency of the magnesium alloy sacrificing anode material.This study provides a certain technical reference for the design of magnesium alloy sacrificing anode.
