传统的铝硬质阳极氧化工艺需要较低的温度和较高的电压，能耗大且工件易烧损。本工作通过在阳极氧化电解液中添加草酸、丙三醇及NiSO4，提高阳极氧化温度上限实现了常温下的硬质氧化，并采用正交试验法对添加剂含量进行优化，获得了最佳的常温硬质阳极氧化工艺。
The traditional process of hard anodic oxidation of aluminum has some shortcomings such as high energy consumption, easy burn, needs of low temperature and high voltage. Oxalic acid, glycerol and NiSO4 were added into the electrolyte of anodic oxidation to raise the temperature limit of anodic oxidation, which made the hard anodizing can be carried out at room temperature. And by using orthogonal experiment method, the content of electrolyte additives was optimized and the best hard anodizing process at room temperature was obtained.
