The anodizing of AZ91D Mg alloys in the solution of different concentration of NaOH has been investigated by ways of voltage-time curve, immersion corrosion experiment, polarization curve, XRD, SEM, EDS and XPS respectively.

• 采用电压-时间曲线、全浸腐蚀实验、极化曲线法、X射线衍射法(XRD)、扫描电镜(SEM)和能量色散谱仪(EDS)等方法研究了AZ91D镁合金在含不同浓度氢氧化钠的阳极化溶液中的阳极氧化行为和膜层的成分、结构。
