摘要
在硫酸电解液中加入适量由羧酸和有机化合物组成的添加剂 ,制得铝合金阳极氧化膜。研究了温度对所得氧化膜厚度和硬度和影响 ,并利用扫描电镜观察了氧化膜的结构。结果表明 ,高温下形成的氧化膜结构松散 ,厚度和硬度低 ,而加入添加剂后 ,氧化膜溶解减慢 ,在高温下所形成的氧化膜的厚度和硬度大大增加。
Anodic oxidation film was prepared on aluminum alloy in sulfuric acid electrolyte. An additive was developed which consists of carboxylic acids and organic compounds. The effect of temperature on thickness and hardness of the obtained anodic oxidation film was studied, structure of the oxidation film was analyzed by SEM. The results show that oxidation film obtained at high temperature has loose structure. Thickness and hardness of the film decrease with the increase of temperature, while the addition of the additive reduces the dissolution of the oxidation film, and increases film thickness and hardness greatly at high temperature.
