摘　　要：将不对称正负脉冲电流应用于铝的普通阳极氧化,研究了不对称脉冲电流氧化参数(正脉冲电流、负脉冲电流、周期比和频率)对铝阳极氧化过程和氧化膜性能的影响。结果表明,在合适的电解参数下采用不对称脉冲电流对铝进行阳极氧化,具有成膜速度快、膜层硬度高等特点。Asymmetric pulse current method was used in the anodic oxidation of aluminum. The influences of the pulse parameters including anodic pulse current, cathodic pulse current, ratio of period, and frequency on the process of anodizing and the performance of the oxide film of aluminum were investigated. The results show that asymmetric pulse current method has many advantages such as fast film forming rate and high hardness of the film.
