摘　　要：简要论述了能有效提高镁合金耐蚀性能的表面改性技术的研究现状及各自的优缺点,包括化学转化膜、阳极氧化、微弧氧化、激光表面处理、化学镀镍及机械研磨化学镀。机械研磨化学镀是一种提高镁合金耐蚀性的最有效的方法,将成为镁合金表面改性技术的一个重要发展方向。The surface modification will play a key role in improvement on the corrosion resistance of magnesium alloys. The present situation of research on the surface modification technologies for the magnesium alloys and their merits and demerits were briefly described,including chemical conversion coating,anodizing,micro-arc oxidation,laser surface treatment,electroless nickel plating and mechanical grinding electroless plating. The mechanical grinding electroless plating is the most effective method to improve the corrosion resistance of the magnesium alloys,and will become an important development direction of the surface modification technologies for the magnesium alloys.
