摘要:
为更好地指导新型硅烷-钼复合无铬钝化膜的工业化生产，研究钝化膜的耐蚀性能，构建皮膜量标准曲线。分别使用X射线衍射仪（XRD）、X射线光电子能谱仪（XPS）分析钝化膜的物相组成和表面元素价态。利用中性盐雾试验和电化学测试，探讨钝化膜的耐蚀性能。采用X射线荧光光谱法（XRF），绘制和构建皮膜量标准曲线。结果表明：硅烷-钼复合无铬钝化膜层中Si、Mo元素能分别与Zn形成化学键，膜层结合性较好。膜层耐蚀性在一定范围内随着膜层皮膜量升高而升高，当皮膜量高于800 mg/m2时，耐蚀性趋于稳定，其耐蚀性与稳定性接近Cr6+。此外，皮膜量与XRF射线强度呈线性关系，斜率为3.413。

Abstract:
In order to better guide the industrial production of the new silane-molybdenum composite chromium-free passivation film, the corrosion resistance of the passivation film was studied, and the standard curve of the coating volume was constructed. X-Ray diffractometer (XRD) and X-ray photoelectron spectrometer (XPS) were used to analyze the phase composition and surface valence states of the passive film. Corrosion resistance of the passive film was investigated by neutral salt spray test and electrochemical test. The standard curve of the film's weight was constructed by X-Ray fluorescence spectrometry (XRF). The results show that the Si and Mo in the molybdenum chromium composite passivation film form chemical bonds with Zn, respectively; and the film has good adhesion. In a certain range, the corrosion resistance of the film increases with the increase of the film's weight. When the film's weight is more than 800 mg/m2, the corrosion resistance of the coatings tends to be stable, and its corrosion resistance and stability are close to Cr6+. Additionally, the weight of the film is linear with the XRF ray intensity, and the slope is 3.413.
