摘　　要：阳极氧化过程中铝合金放热导致槽液温度升高,会对膜层生长有较大影响。本文对6061、6063、2024及7075铝合金进行宽温阳极氧化处理,对其膜层厚度以及表面状态进行研究,结果表明铝合金合金元素对阳极氧化膜生长及结构有重要的影响,Cu、Mn等金属合金元素阻碍了铝合金氧化膜的生长,当电解液温度较高时,这些合金元素会使膜层起粉而导致膜层不合格。Temperature rise during aluminum alloy anodic oxidation has a bad influence on the oxidation film growth. Film thicknesses and surface pattern of 6061,6063,202,7075 aluminum alloys after wide temperature anedic oxidation were studied. The results indicated that alloy elements played an important role in the anodic oxidation of the aluminum alloys, heavy alloy elements, such as Cu and Mn, stunt the film growth, even cause powder on the film when the electrolyte temperature is high.
