铝铜合金阳极氧化发展概况

Current status of anodic oxidation of aluminum-copper alloy

铝铜合金由于重量轻、机械强度高而得到广泛应用。然而 ,由于铜的存在使铝铜合金的演技氧化变得困难。分析了铜含量对铝铜合金阳极氧化的不良影响 ,并总结了集中改进措施如电解液成分、温度。

Aluminum-copper alloy has been widely adopted for its low weight and high mechanical strength, but the existence of copper makes the anodizing of aluminum-copper alloy difficult. Herein, the detrimental effects of copper on anodic oxidation of aluminum-copper alloy were discussed, and modified measures were introduced such as electrolyte composition, temperature, agitation and the way of imposed current.
