| 摘 要： | 目的研究不同腐蚀环境条件下铝合金阳极氧化膜层的防护作用及失效规律。方法采用中性盐雾、酸性盐雾试验方法进行加速试验,对无划线试样腐蚀外观和附着力以及有划线试样的腐蚀形貌等进行检测和考核分析。结果获得了4种铝合金材料阳极氧化膜层在不同试验环境条件下的防护性能、腐蚀失效、附着力变化以及抗腐蚀扩展性能等试验数据。结论铝合金材料类型对未封闭处理的阳极氧化膜的耐腐蚀扩展性能影响明显。封闭处理能够提高铝合金阳极氧化膜的综合防护性能。

| Abstract: | Objective To study the protective effect and failure behavior of anodic oxidation film on aluminum alloy in different corrosive environments. Methods Accelerated tests were conducted by neutral salt spray test (NSS) and copper-accelerated acetic acid salt spray (CASS). The corrosion morphology of scratched samples and the corrosion appearance and adhesion of non-scratched samples were examined and analyzed. Results Protective performance, corrosion failure, changes in adhesion and anti-corrosion propagation performance of anodic oxide coatings of four kinds of aluminum alloy materials in different test environments were obtained. Conclusion Types of aluminum alloy have significant effects on anti-corrosion propagation performance of the unsealed anodic oxide coatings. Sealing treatment can significantly improve the comprehensive protective properties of anodic oxide film on aluminum alloy. |
