摘　　要：镁合金在自然环境中容易腐蚀,许多表面防护技术虽然能大幅度提高镁合金的耐蚀性能,但同时也会影响其表面导电性能,限制镁合金在3C电子产品壳体结构件方面的应用。因此,需要采用合适的表面防护技术对镁合金进行耐蚀导电处理。综述了近年来镁合金化学转化、电镀/化学镀、磁控溅射、涂覆有机涂层几种耐蚀导电防护技术,介绍了各技术在镁合金耐蚀导电领域的最新研究进展,并针对各项技术面临的主要问题以及未来主要发展趋势进行了总结和展望。Magnesium alloys are easy to corrode in the natural environment. Although the corrosion resistance of magnesium alloys can be improved significantly by many surface protection technologies, their surface conductivity will also be affected, which limits their application in the shell structure of 3 C electronic products. Therefore, it is necessary to adopt appropriate surface protection technology to conduct corrosion-resistant and conductive treatment on magnesium alloys. In this paper, several corrosion-resistant and conductive protection technologies of magnesium alloy in recent years, such as chemical conversion, electroplating/electroless plating, magnetron sputtering and organic coating were reviewed. Then, the latest research progress of various technologies in the field of corrosion resistance and electrical conductivity protection of magnesium alloys was introduced. Finally, the main problems faced by these research technologies and the main development trends in the future were summarized and prospected.
