| 摘 要： | 研究了ＺＭ５铸造镁合金微弧氧化膜的生长规律，初步分析了氧化膜生长机理。初始阶段，氧化膜向外生长速度大于向内生长速度。达到一定厚度后完全转向基体内部生长。氧化膜具有表面疏松层和致密层两层结构，致密层最终可占总膜厚的９０％。

| Abstract: | The growth regularity of ceramic film in microarc oxidation on ZM5 cast magnesium alloy was studied, and the formation mechanism of the oxidation film was discussed. During the first stage of oxidation, the growth rate of film toward the external surface is higher than that toward the substrate. When the oxide film with a certain thickness is formed, the process of oxidation shifts onto substrate, and the geometry size of sample would merely change in the stage. The oxide film consists of the loose layer and the compact layer, and the latter can finally reach 90 percent of total thickness of film. |
