为了解决镁合金材料在海洋性气候条件下抗蚀性低、耐磨性差、与有机涂层结合力不强等问题,选择ZM5为研究对象,分别进行化学膜处理、MIL-M-3171、DOW17阳极氧化处理和微弧氧化.检测了阳极氧化和微弧氧化膜层的表面形貌和元素组成,测试对比了3种处理工艺膜层的显微硬度、中性盐雾条件下的抗蚀性能和有机涂层的结合力.结果表明,经微弧氧化和喷漆处理后的镁合金件综合性能最佳,适用于海洋性气候环境.

In order to solve the problem of magnesium alloy low corrosion resistance,poor wear resistance and poor bond strength with organic coatings under marine climatic,ZM5 was selected for the research,three different surface treatment processing,micro-arc oxidation,chemical film and MIL-M-3171,DOW17 anodizing were used on the magnesium alloy,of which DOW17 and micro-arc oxidation sample were subjected for EDX and morphologies analyzed.Compared three different processing layers properties under the testing of neutral salt spray,micro-hardness,bond strength with organic coatings.Testing results indicated the micro-arc oxidation processing post with paints treated on magnesium alloy obtained the best overall performance,suitable for application in marine climate environment.
