一、前言飞机上所用的各种铝材一般都需要进行化学氧化或阳极化处理,特别是对胶接、涂漆等工艺,铝合金阳极化处理可以提高胶层或漆层的结合力。进一步研究表明,经过阳极化处理的铝材表面,随其表面状态的不同(新鲜表面还是放置中陈化或污染了的表面)将会极大地影响到胶层和漆层的结合强度,这是因为阳极化时生成的氧化膜具有许多微孔,这些微孔受到水份、灰尘、油污的污染后容易被堵塞, I. INTRODUCTION The various types of aluminum used in the aircraft generally require chemical oxidation or anodization, especially for the gluing, painting and other processes. The anodized aluminum alloy can improve the adhesion of the adhesive layer or the paint layer. Further studies have shown that the anodized aluminum surface, depending on the surface conditions (fresh surface or placed in the aging or contaminated surface) will greatly affect the adhesive layer and paint the strength of the bond, which is Because the anodized oxide film has many pores, these pores by water, dust, oil pollution easily blocked,
