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。
The characteristics of marine corrosion were analyzed, the morphology and corrosion resistance of mi- cro-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.
