摘　　要：镀锡板钝化膜的组织结构影响后续涂漆的附着力。利用光电子能谱(XPS)分析了镀锡板钝化膜表层和内部的组织结构,从而分析其对镀锡板涂漆附着力的影响。结果表明:阴极钝化过程中钝化液夹杂杂质离子造成镀锡板钝化膜含Cl元素,Cl含量较高时涂漆附着力差;钝化膜中Cr(OH)3对涂漆附着力影响较大,其含量越高,涂漆附着力越差;钝化膜表层含少量的金属Cr对于提高镀锡板涂漆附着力有利,而钝化膜中总Cr含量对涂漆附着力影响较小。The superficial and inner microstructure of passivation film on tinplates was analyzed by means of X-ray photoelectron spectroscopy(XPS),and its effect on the adhesion of lacquer was examined.It was found that Cl coming from the passivation fluid was introduced into the passivation film as an impurity during cathodic passivation process.A higher content of Cl led to significantly decreased adhesion of the lacquer.Cr(OH)3 in the passivation film had a great effect on the adhesion of the lacquer.Namely,the higher the content of Cr(OH)3 was,the weaker the adhesion of the lacquer would be.In the meantime,a small amount of superficial metallic Cr was beneficial to increasing the adhesion of the lacquer,but the total content of Cr in the passivation film had a minor effect on the lacquer adhesion.
