航空用铝合金表面处理的研究现状与展望

摘要

Application of aluminum alloy is briefly described in construction industry, automobile industry, and aviation industry totally. The development of adhesive bonding at domestic and foreign countries is introduced. Then, the purpose, mechanics, classification of surface treatment of aluminum alloy used in bonding structure is reviewed. At the same time, the parameters of the surface treatment which affect the surface quality and the methods of modern surface analysis are introduced too. Meanwhile, the popular and most sophisticated technology in aviation industry, the characteristic and applications of orthophosphoric acid anodization are also discussed At last, the trend in this field is presented.%全面介绍了国内外铝合金在建筑、汽车、航空航天等行业的应用及研究进展.主要阐述了航空航天领域结构胶接在国内外的发展状况、胶接用铝合金表面处理方法的目的、表面处理的机理及分类、影响表面处理质量的工艺参数、现代表面分析技术等.并对近年来国内外应用最广、技术最成熟的磷酸阳极化表面处理技术的应用及优缺点进行了分析,并展望了该领域研究的发展趋势.
