摘　　要：利用金相显微技术、能谱分析和扫描电镜等测试手段 ,研究了合金中元素Mg的含量对牺牲阳极Al Zn In Si Mg系合金的晶粒尺寸、偏析相等微观组织的影响 .结果表明 :添加 1.6 %～2 .0 %Mg的晶粒细化明显 ,偏析相MgZn2 在含 1.0 %Mg的合金中开始出现 ,含 1.6 %Mg时分布均匀 ,并随Mg的不断增加而增加 .Microscope,Energy spectrum analysis and Scanning electron microscope (SEM) were used to study the effect of deferent Mg on the grain size,the morphology and amount of segregative phase of Al Zn In Si Mg alloy sacrificial anode.The results showed:increasing Mg to 1.6%～2.0%,the grain size of the alloy became the smallest;the segregative phase MgZn 2 appeared at 1.0% Mg and became well distributed at 1.6% Mg and increased by adding Mg.\;
