摘　　要：应用极化曲线、电化学阻抗方法研究了经表面处理后的镁合金的电化学行为。用扫描电镜仪(SEM)观察了合金微观形貌,能谱仪(EDS)探测表面元素含量分布。讨论了表面处理后的镁合金表面元素对合金化学性能的影响。结果表明,处理后的镁合金比未处理的镁合金电化学性能有了较大改善。The elechtrohemical behavior of the treated magnesium alloy were investigated by polarization curves and electrochemical impedance spectroscopy techniques. The alloy microstructure and surface morphology were observed by SEM, and the element distribution on surface was researched by EDS. The effect of the surface treatment on electrochemical behavior of magnesium alloy was discussed. The results show that the treated magnesium alloy exhibits much better chemical performance than untreated alloy.
