| 摘 要： | 用静态失重法、金相显微镜、扫描电子显微镜等方法研究了不同含量的Sn对Mg-6Al-1.2Y-0.9Nd镁合金的微观组织以及在3.5%NaCl腐蚀介质中的腐蚀速率和表面腐蚀形貌的影响。结果表明，添加1%Sn 时，合金的晶粒得到了明显的细化，组织和成分更加均匀；当Sn含量大于1%时，合金的析出相增多，并出现粗化、偏聚的趋势。在NaCl溶液中，合金的腐蚀速率均随着Sn含量的增加呈现先降低后增加的趋势，其中当Sn含量为1%时合金的腐蚀速率均达到最低，耐蚀性能得到明显地改善。

| Abstract: | Effects of Sn addition on corrosion rate of Mg-6Al-1.2Y-0.9Nd magnesium alloy in 3.5%NaCl solution were studied by the static mass-loss tests.The microstructures of the alloys were observed by optical microscope and the morphologies of corrosion surface were analyzed with scanning electron microscopy.The results indicated that with the addtion of 1%Sn,the crystal grain size of the Mg-6Al-1.2Y-0.9Nd magnesium alloy was obviously refined,the microstructure was more homogeneous.But when the addition of Sn is m... |
