Abstract:将稀土元素Nd添加到Mg-2Zn-3Sn合金中，采用金属型铸造制备了Mg-2Zn-3Sn-xNd(x=0, 0.5, 1, 2,质量分数，%)合金，采用光学显微镜(OM)、扫描电镜(SEM)及X射线衍射(XRD)等分析了铸态Mg-2Zn-3Sn-xNd合金的微观组织，应用电化学测试和Hank’s溶液静态浸泡测试研究了其耐腐蚀性能。结果表明，铸态Mg-2Zn-3Sn-xNd合金由α-Mg相、MgSnNd相、Mg_2Sn相和少量的MgZn相组成。与Mg-2Zn-3Sn合金相比，Mg-2Zn-3Sn-xNd合金的晶粒得到明显细化。少量Nd(0.5%、1%)可提高Mg-2Zn-3Sn合金的耐腐蚀性，但当Nd的添加量较高时(2%),电偶腐蚀加剧，合金的耐腐蚀性能降低。Mg-2Zn-3Sn-0.5Nd合金的耐腐蚀性能最佳，说明适量Nd可改善Mg-2Zn-3Sn合金的耐腐蚀性。
