摘    要:回顾镁合金阳极氧化历史, 介绍制备工艺、 电解液组成及作用, 同时对镁合金阳极氧化机理进行探讨。 随着人类环保意识的增强, 世界能源的紧缺和氧化设备的不断更新, 认为电参数如频率、 占空比、 电压和电流密度对氧化膜性能的影响、 阳极氧化电流效率的测定、 氧化膜扩散规律的研究和环保型电解液的开发为未来镁合金阳极氧化研究的重点。

Abstract: The history of anodic oxidization on magnesium and its alloys was simply reviewed, and its treating process, compositions and functions of electrolyte were introduced comprehensively. In addition, the mechanism of oxidization on magnesium was discussed. With the development of human awareness on environmental protection and the scarcity of world resources and upgrade of anodization equipment, the effects of electric parameters on properties of anodic coating, measurement of current efficiency, study of diffusion regularity for anodic coating formation and development of environmentally friendly electrolyte were put forward about anodization.
