摘　　要：针对镁合金微弧氧化膜的耐腐蚀性需求,综述了近年来国内外在镁合金微弧氧化膜腐蚀特性方面的研究进展。较系统的总结并探讨了点滴试验、盐雾试验、电化学试验和无损检测等镁合金微弧氧化膜的耐蚀性表征方法,介绍了镁合金微弧氧化膜的腐蚀失效过程及其在不同介质中的腐蚀行为,指出镁合金微弧氧化膜在不同介质中的腐蚀行为研究仍有不足,今后的研究重点应放在针对不同腐蚀环境膜层的腐蚀行为研究上。Research progress of corrosion characteristics of the micro-arc oxidation coating on magnesium alloy was reviewed. Dropping corrosion test, salt spray test, experiment of erosive electrochemistry, nondestructive test and other characterization methods of corrosion resistance were summarized and discussed. The corrosion failure progress and the corrosion behavior in different corrosion environment were introduced. The deficiencies and the research emphasis in the future of the micro-arc oxidation coating on magnesium alloy were pointed out.
