【摘要】 通过金相观察、扫描电镜、XRD、静态失重法以及极化曲线等方法,研究了稀土元素Nd对铸态ZK60镁合金组织和腐蚀行为的影响。结果表明:Nd的加入细化了微观组织,产生了Mg12Nd相,减缓了ZK60镁合金在NaCl溶液中的腐蚀速率。进而探讨了显微组织与腐蚀性能之间的关系。更多还原

【Abstract】 The effect of Nd on microstructure and corrosion behavior of ZK60 magnesium was studied by OM,SEM,XRD,static weight-loss test and polarization curve test. The results showed that Nd represents the ability to refine the microstructure and improve corrosion resistance of ZK60 magnesium alloy obviously .The relationship between microstructure and corrosion performance was discussed.更多还原
