本文介绍了铝材表面处理的目的与要求、经过各种机械和 (电 )化学方法处理后的表面特性 ,如表面形貌、表面粗造度、表面化学组成、表面润湿特性、表面氧化物的环境稳定性及其粘接特性。其中以磷酸阳极化作最后表面处理工序获得的效果最好 ,在此前的化学处理工序基本不影响最后表面处理效果 This article describes the purpose and requirements of aluminum surface treatment, after a variety of mechanical and (electrical) chemical treatment of the surface properties, such as surface morphology, surface roughness, surface chemical composition, surface wetting characteristics, surface oxides Environmental stability and adhesive properties. Among them, phosphoric acid anodization is the best for the final surface treatment. In the previous chemical treatment, the effect of the final surface treatment is not affected
