镁合金电极上生成阳极氧化膜的保护技术，使电极耐大气腐蚀的性能大大优于用铬酸盐膜保护的镁电极．阳极氧化工艺条件不同，镁电极的耐腐蚀性和电压滞后性能不同，本文讨论了膜的组成、形态、厚度等对性能的影响
The corrosion resistance of Mg alloy electrode with anodized film in atmosphere is bigger than that of the Mg alloy electrode with chromate film. The corrosion resisance and voltage delay of such electrode with anodized film in NaCl solution changed with anodizing comdition. The effects of composition, morphology and thickness of the anodized film on the peoperty of Mg alloy electrode are discussed.
