摘　　要：铝及其合金因其具有较好的力学性能、易加工等特性,在工业发展的各个领域得到了十分广泛的应用。对其表面处理后可以更好的提高其各方面性能,阳极氧化是最常见的铝及铝合金材料表面处理方法,通过阳极氧化阻挡层的形成及溶解、多孔层的形成,氧化膜形状为一个细长的空心柱体,尺寸一般小于100nm,微孔孔径一般小于20nm,微孔的密度惊人,达到760亿个/平方厘米,使得铝氧化膜具有较好的、电绝缘性、多孔性、耐磨性、耐蚀性、绝热性等性能,使得其在工业生产中应用更加广泛。Aluminum and its alloy because of its good mechanical properties,easy processing,in the areas of industrial development has been widely used.On its surface after treatment can improve its better performance in all respects.Anodic oxidation is the most common surface treatment of aluminium and aluminium alloy material,through the formation and dissolution of anodic oxidation barrier layer,porous layer,the formation of oxide film shape is the hollow cylinder of a long and thin,generally less than 100 nm,microporous aperture generally less than 20 nm,the density of pore,76 billion per square centimeter,makes the aluminum oxide film has good,electrical insulation,porous,wear resistance,corrosion resistance,insulation performance,making them more widely used in industrial production.
