摘要
制备了一种稀土 Zn 1 5Al合金 ,并用人工海水浸泡合金进行了腐蚀实验 ,借助金相与扫描电镜观察其腐蚀形貌及组织变化情况 .结果表明 :适量稀土的加入可细化Zn 1 5Al合金的铸态组织 ,而对合金的耐蚀性能无显著改善 ;当微量Cu、Mg及稀土复合添加时可显著改善合金的耐蚀性能 .通过实验确定了Ce的最佳含量为 0 .1 % (质量分数 ) .
The preparation of an alloy RE Zn Al15 was reported in this paper. The corrosion resistant properties of the alloy were tested by soak in sythesised marine. The corrosion surface and microstructure change were investigated by means of OM. It is shown that the as cast structure of Zn Al15 alloy can be refined by addition of rare earth elements, but an obvious improvement of the corrosion resistant properties of the alloy was not observed. When the micro Cu, Mg and RE were added complexly, the corrosion resistance can be considerably increased. The experiment determined that the optimum content of Ce in the alloy should be 0.1%. [
