摘　　要：要:镁及其合金的化学活性高,耐蚀性能差,阻碍了镁合金应用领域的拓展.采用预处理+有机涂装法制备复合有机涂层,综合了多种表面处理方法的优点,可获得耐蚀性能良好的镁合金保护涂层,是解决镁合金耐蚀问题的重要研究方向,具有巨大的应用前景.本文对几种镁合金复合有机涂层的制备原理和研究现状进行了综述,并提出了其发展方向.High activity and poor corrosion resistance of magnesium and its alloys hindered their applications. A complex and organic coating prepared by pretreatment plus painting integrates the advantage of various surface treatment methods, which could yield a good corrosion resistant protective coating for magnesium alloy, and the complex and organic coating is an important research orientation to solve the corrosion problem of magnesium al- loy, and has a great application prospect. This paper introduces the preparation principle and present status of several complex organic coatings of magnesium alloy, and proposes their development prospects.
