摘　　要：镁合金因其低密度、高比强度、优异的电磁屏蔽性能和可回收性等特点,在航空航天和3C电子产品等领域具有广泛的应用前景。然而,镁合金的高化学活性导致其受到腐蚀,并且耐磨性有限,限制了其广泛应用。微弧氧化技术被广泛认为是解决这些问题的有效途径,通过在镁合金表面生成陶瓷氧化膜,从而提高其耐磨性和耐腐蚀性。本文总结了近年来微/纳米颗粒改性镁合金微弧氧化膜层性能的研究进展,简要介绍了镁合金微弧氧化膜层的形成机理,重点分析了膜层组织演变、摩擦磨损性能及耐腐蚀性能等关键指标以及微弧氧化技术在镁合金表面高性能开发的研究方向,为未来的研究工作提供有益的参考和借鉴,进一步促进镁合金的应用与发展。Magnesium alloys have extensive application prospects in fields,such as aerospace and 3C electronic products due to their low density,high specific strength,excellent electromagnetic shielding performance and recyclability.However,the high chemical reactivity of magnesium alloys makes them prone to corrosion and limited wear resistance,which restricts their applications.The micro-arc oxidation technique is widely regarded as an effective method to address these issues by generating ceramic oxide coatings on the surface of magnesium alloys,thereby improving their wear resistance and corrosion resistance.This article provided a summary of the recent research progress on the performance of micro/nano-particle-modified magnesium alloy micro-arc oxidation coatings.The formation mechanism of micro-arc oxidation coatings on magnesium alloys was briefly introduced,with a focus on key indicators,such as coating structure evolution,friction and wear performance,and corrosion resistance.The research direction for developing high-performance surfaces of magnesium alloys using micro-arc oxidation technique was presented,offering valuable references for future research and promoting the application and development of magnesium alloys.
