| 摘 要： | 通过电化学分析测量镁合金微弧氧化陶瓷层和阳极氧化陶瓷层的交流阻抗图谱，稳态电流／电位曲线，并对得出的交流阻抗值和腐蚀电流进行比较，结果表明，与阳极氧化处理比较，镁合金经营微弧氧化处理后交流阻抗值增大，腐蚀电流降低，微弧氧化陶瓷层特有的微观结构是其耐蚀性显著提高的主要原因。

| Abstract: | Corrosion behaviors of magnesium alloy ceramic layer formed by micro arc oxidation and anodic oxidation through electrochemical methods as EIS and steady state I/E curves. The results showed that comparing to anodic oxidation, the impedance of micro arc oxidation magnesium alloy increased and the corrosion current decreases. Special microstructure of ceramic layer formed by micro arc oxidation was the main reason of high corrosion resistance. |
