【Abstract】 Low temperature operating was required in conventional hard anodic oxidation of aluminum which result in high energy consumption. Hard anodic oxidation of aluminum alloy under direct pulsed current at temperature of 5-10℃ was studied. The effect of additive A and B on oxidizing parameters and properties of the obtained oxide film was studied. The temperature and rate of oxidation were raised by the addition of A and B, and oxide film with excellent properties was obtained. Results show that the process has low cost and high productivity.更多还原
