镁合金化学防腐膜制备工艺的研究进展

The Research of Preparation Technology of Magnesium Alloys Corrosion Protection Film

镁合金是目前最轻的金属材料,其耐蚀性较差,使它的应用受到很大的限制.综述了镁合金的化学转化处理、电镀、表面微弧氧化及有机涂层等防腐工艺的研究进展,并展望了镁合金防腐膜的发展趋势.

Magnesium alloys is the lightest metal materials . It is the poor corrosion resistance that limits its extensive applications. In this paper,the research progress of chemical corrosion coating used for magnesium alloys,such as chemical conversion processing ,micro-arc oxidation,electroplating and organic coating were summarized,and the development trends of chemical corrosion coating technology used for magnesium alloys was also prospected.
