以磷酸为主要成份的除锈抗蚀剂广泛用于钢铁表面处理.经适当的磷酸混合液浸、喷或涂刷后的铁表面对漆和树脂的附着性能良好,所形成的表面磷酸化层能增强材料的耐腐蚀性和耐磨损性. 现代表面分析技术,其中特别是俄歇电子谱(AES)和X射线光电子谱(XPS),在腐蚀科学研究中已表明是分析表面抗腐蚀层的有效工具.本文报导用XPS方法分析铁表面磷酸化层的结果,阐明磷酸化层的成分和磷酸混合液与铁表面间的作用. 一、实验锉除锡、锌镀层的马口铁或白铁片,用金相砂纸抛光后,在无水乙醇中超声清洗,晾干后进行磷酸化处理.所用磷酸化液的成份列于表1.新配制的磷酸化液呈淡红色,
Phosphoric acid as the main component of the rust inhibitor is widely used in steel surface treatment.After appropriate phosphate mixture immersion, spraying or brushing the iron surface of the paint and resin adhesion is good, the formation of the surface of the phosphorylated layer Can enhance the material’s corrosion resistance and wear resistance Modern surface analysis techniques, of which in particular Auger electron spectroscopy (AES) and X-ray photoelectron spectroscopy (XPS), have been shown in corrosive scientific studies to analyze surface corrosion resistant layers Of the effective tools.This paper reports the results of XPS analysis of iron surface phosphorylation layer to clarify the composition of the phosphorylated layer and phosphoric acid mixture and the role of the surface between the iron.First, the experimental file except tin, zinc plated tinplate or white iron sheet, Polished with metallographic sand paper, ultrasonic cleaning in anhydrous ethanol, dried and then phosphorylated.The composition of the phosphating solution used is shown in Table 1. The newly prepared phosphorylation solution was light red,
