采用载波钝化方法对AZ91D镁合金进行载波钝化，使用原子力显微镜（AFM）、接触角仪(FTA)仪器和X射线光电子谱仪（XPS）研究了载波钝化对AZ91D镁合金表面特性的影响。结果表明：载波钝化后AZ91D镁合金表面生成一层均匀且致密的表面膜，内层由 MgO和少量Al2O3组成，外层由Mg(OH)2、MgO和少量 Al(OH)3组成。
AZ91D magnesium alloy was treated by alternating voltage (AV) modulated passivation technique. Atomic force microscopy (AFM), First ten angstroms (FTA) contact angle-meter and X-ray photoelectron spectroscopy (XPS) were employed to investigate the influence of AV-modulated passivation on the surface properties of the films formed on the AZ91D magnesium alloy after AV-modulated passivation. The results showed that a uniform and stable film was formed after AV-modulated passivation. The surface films on the samples after AV-modulated passivation consist of an inner layer rich in MgO, with a little Al2O3，and an outer layer of Mg(OH)2，MgO with a little Al(OH)3.
