| 摘 要： | 采用室内海水浸泡试验、电偶试验等方法研究了6061铝合金微弧氧化层厚度和封孔处理对其耐海水腐蚀性能的影响。试验发现，微弧氧化后，铝合金在海水中的腐蚀形貌为点蚀，封孔处理可明显抑制点蚀的发生，厚度变化对耐蚀性影响不大。与铜合金偶合后，微弧氧化铝合金的腐蚀速率增加，因此在实际使用中应尽量避免这2种材料的电接触。

| Abstract: | The effect of microarc oxidation thickness and sealing treatment to seawater corrosion resistance of 6061 aluminum alloys were studied with laboratory seawater immersion test and galvanic corrosion test.It was found that there were pitting corrosion on microarc oxidation aluminum alloy and the pitting was reduced after sealing treatment.Corrosion of microarc oxidation aluminum alloy was accelerated when coupled with copper alloy.Therefore,the galvanic corrosion with copper alloy should be avoided. |
