| 摘 要： | 分析了海洋腐蚀的特点,对比了微弧氧化膜与几种常用防护膜层的形貌和耐蚀性,研究了微弧氧化膜的绝缘性能及其经喷漆、电泳后的耐蚀性能。结果表明:通过微弧氧化在铝、镁及其合金表面生成具有陶瓷组织的氧化膜,然后进行喷涂或电泳处理,可有效防止点蚀、缝隙腐蚀及电偶腐蚀的发生,是海洋环境中铝、镁合金防腐蚀的一条新途径。

| Abstract: | The characteristics of marine corrosion were analyzed,the morphology and corrosion resistance of micro-arc oxidation film and several common protective film were compared,the insulation property of micro-arc oxidation film and corrosion resistance after painting and electrophoresis were studied.The results show that: the oxide film with ceramic is formed on the surface of aluminum,magnesium and its alloys by micro-arc oxidation and then it is treated by spraying or electrophoresis process,which can effectively prevent pitting,crevice corrosion and galvanic corrosion occurs.It is a new way to prevent the corrosion of aluminum and magnesium alloy in the marine environment. |
