摘　　要：以高电位镁合金牺牲阳极的生产工艺为根据,研究了Mn、Zn等元素对镁阳极电流效率的影响。结果表明,当w(Fe)<0.005%时,随着锰含量增加,电流效率逐渐降低;w(Zn)=0.04%时,牺牲阳极的电流效率最高。利用高纯镁可以直接制备出符合国家标准电性能要求的阳极。根据研究结果,设计并成功制备了3种不同成分的高电位镁合金牺牲阳极:低锰阳极、锌镁阳极和纯镁阳极。According to the production technology of magnesium alloy sacrificial anode with high electric potential, research was conducted on the effect on the current efficiency of magne- sium anode with addition of mananese and zinc elements. Results show that with the increase of Mn content,the current efficiency decreases when iron content is under 0. 005% ;the current efficiency of sacrificial anode is highest when the content of zinc is 0.04%. The anode with the electrical properties in conformity with the national standard was produced by using high purity magnesium. According to these results, three kinds of novel anodes were designed and prepared successfully：low manganese magnesium anode,Zn-Mg anode and pure magnesium anode.
