摘　　要：封孔是进一步提高镁合金阳极氧化膜耐蚀性的有效方法,主要方法有沸水、铬酸盐、硅酸盐、磷酸盐、溶胶-凝胶以及有机物封孔,本文对以上几种方法进行了全面综述。鉴于镁合金阳极氧化膜封孔技术目前还不成熟,需加强这方面研究以满足镁合金阳极氧化工业应用。Sealing is an effective method to further improve the corrosion resistance of anodic coatings formed on magnesium alloys.The main sealing methods include boiling water,chromate,silicate,phosphate,sol-gel and organic coating.Several sealing methods as above were reviewed comprehensively.In view of sealing technology underdeveloped on anodic coatings of magnesium alloys at present,the authors propose the research on the area should be reinforced in order to meet the industry application of anodizing on magnesium alloys.
