摘要:

通过化学转化法在ADC12铝合金表面制备出新型硅锆复合转化膜。利用硫酸铜点滴实验与极化曲线测试对胺基双硅烷含量进行优化，利用场发射扫描电镜 (FESEM) 对转化膜的微观形貌进行分析，采用Fourier变换红外光谱分析仪 (FT-IR) 与X射线光电子谱 (XPS) 研究了转化膜的结构与成分并对成膜过程进行了分析，利用电化学测试、中性盐雾实验研究转化膜的耐蚀性能。结果表明：60%胺基双硅烷转化膜的耐蚀性能最优。胺基双硅烷的引入明显改善了转化膜的均匀性和致密性。胺基双硅烷大大提升了转化膜的耐蚀性能。相较于锆转化膜，硅锆复合转化膜的容抗弧半径增加了3倍以上；低频阻抗值增加了3倍以上；耐盐雾时间提升了20倍以上。

Abstract：

A new type of Si-Zr composite conversion film was prepared on the surface of ADC12 aluminum alloy by chemical conversion method. The content of aminobissilane was optimized based on the results of copper sulfate dropping test and polarization curve measurement. The microstructure, chemical composition and crystallographic structure of the conversion film were characterized by means of field emission scanning electron microscopy (FESEM), X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FT-IR). The corrosion resistance of the passive film was studied by electrochemical test and neutral salt spray test. The results show that the introduction of aminobissilane can significantly improve the uniformity and compactness of the conversion film; thus aminobissilane greatly improves the corrosion resistance of conversion films; among others, the corrosion resistance of the conversion film with 60% aminobissilane is the best. Compared with the Zr conversion film, the capacitive reactance radius and the low frequency impedance value of the Si-Zr composite conversion film increase by more than 3 times respectively, and in consequence, the life-time of salt spray corrosion resistance increases by more than 20 times.

Key words： ADC12 aluminum alloy aminobissilane silicon-zirconium composite conversion film corrosion resistance salt spray test
