摘　　要：镁合金质轻,具有许多优良的性能,应用日益受到关注,但耐磨、耐蚀性差却制约着其广泛应用,需进行合适的表面处理以提高防护性能。综述了镁合金的主要应用及其表面处理研究的进展。目前,镁合金已广泛应用于汽车、电子、航空、航天等领域,所采取的表面处理方法主要有化学处理、阳极氧化、金属涂层、有机涂层、微弧氧化等,重点介绍了镁合金微弧氧化的研究进展,并基于在这方面所做的研究工作分析了今后镁合金微弧氧化研究的发展趋势。最后,提出了今后镁合金表面处理研究的发展方向。Magnesium （Mg） alloys are promising materials for a number of applications due to their combination of low density and lots of excellent properties, however, the relatively high corrosion susceptibility and poor wear resistance of Mg alloys prevent their widespread use in many fields, it is necessary to utilize suitable surface treatment to promote their properties. The application and surface treatment research progress of Mg alloys are described. Up to date, Mg alloys are being increasingly applied to various industries like auto, electron, aviation and spaceflight, etc. ,a good number of surface modification procedures such as chemistry treatment, anode oxidation, micro-arc oxidation （MAO）, etc. have been developed and used with a reasonable degree of success in different applications. The progress of the MAO treatment on Mg alloys are emphasized to be introduced, the development trend of the MAO treatment on Mgalloys in future is analysed basing on the author＇s research work about the MAO treatment on Mg alloys; In the last part of the paper, the prospect of surface treatment research and development of Mg alloys in future is presented.
