镁合金表面处理工艺耐蚀性研究

Research on Antieorrosive Surface Treatment of Magnesium-Alloy

镁合金因其优秀的综合性能而广泛应用于结构材料和电子产品壳体，但因其极易被腐蚀，提高其耐蚀性有很大实用价值。作者张先锋和周宝瑜通过盐雾试验和电化学分析试验比较了微弧氯化处理与两种传统镁合金处理方法——铬化处理和阳极氯化处理后镁合金耐蚀性能的差别，并通过分析三种工艺处理后所形成膜层的微观结构，解释了镁合金徽弧氧化陶瓷层的耐蚀性忧于铬化处理和阳极氯化处理的原因。

Magnesium - alloy is widely used as structure materials and for electric devises ,but it is easy to be corroded ,Thus. it is of great importance to improving its anticorrosive ability .Zhang Xianfeng and Zhou Baoyu introduce and explain the ceramic coat anticorrosive ability can be improved through arc oxidiation treatment with compare to the traditional treatments-chromizatinn and anodic treatments through salt fog spray test and electrochemicalanalysis.
