摘要/Abstract

摘要： 通过钛盐与磷酸盐体系复配的方法，在镀锡层表面得到了一种钛-磷复合体系钝化膜. 利用扫描电子显微镜(SEM)、X射线光电子能谱 (XPS)、盐雾试验、Tafel极化曲线和EIS交流阻抗谱测试等方法，研究了所得钝化膜的表面形貌、组成与耐蚀性能. 结果表明，得到的钝化膜层的主要组成成分为Ti₃(PO₄)₄nH₂O和TiO₂，在镀锡层表面结晶细致并有封孔的作用，因此有很好的耐蚀性能.

关键词: 电镀锡, 钛盐, 磷酸盐, 无铬钝化, 耐蚀性

Abstract: A passivation film was prepared on tinplate surface with a composite passivating agent made of titanate and phosphate. The surface morphologies, chemical compositions and corrosion resistances of the passivation films were characterized by scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), salt spray test, Tafel polarization measurement and electrochemical impedance spectroscopy (EIS). The results were compared with those films untreated and treated with titanate or phosphate passivation. It was shown that the titanate and phosphate passivation film was mainly composed of Ti₃(PO₄)₄·nH₂O and TiO₂. The finely crystallized surface could seal holes, therefore, a good passivation performance on tinplates could be achieved.

Key words: tin plating, titanium salt, phosphate, Cr free passivation, corrosion resistance
