| 中文摘要: |
| 目的 通过加入一种合成缓蚀剂提高锆化液防锈性能。 方法 将 P2 缓蚀剂磷酸三乙醇胺加入到锆化液中处理铝合金，使其表面形成一层新型锆化膜。用扫描电镜(SEM)分析处理后样品放大 20 000倍的表面，并与原液处理的样品进行对比，通过能谱(EDS)及 XRD 分析微团成分，辅助使用硫酸铜点滴试验判断耐腐蚀能力的增强程度，并用百格试验测试处理后表面对漆膜的附着力变化，通过酸性盐雾试验(CASS)分析新型锆化膜处理后的附着力变化程度。 结果 使用加入 P2 缓蚀剂的锆化液的辅助硫酸铜点滴实验，较原样颜色变化所用的时间提高了 48 s， 用加入缓蚀剂的锆化液处理的样品中， 氧元素较原样品中氧元素减少了一半，判断微团为氧化微团且在加入缓蚀剂的锆化液处理后大量减少，百格实验效果相当，能通过 480 h 的 CASS。 结论 使用添加 P2 缓蚀剂的锆化液处理铝合金， 能增强其耐腐蚀性能。 |

| Objective To improve the rust resistance of zirconium solution by adding a composite corrosion inhibitor. Methods By adding phosphoric acid triethanolamine P2 corrosion inhibitors to the zirconium solution for treatment of aluminum alloy, a layer of new zirconium film was formed on the surface. Scanning electron microscopy (SEM) was used to analyze the surface of the sample after magnifying 20000 times, and compared with concentrate processing samples. Energy spectrum (EDS) and XRD were used to analyze the components, auxiliary copper sulfate spot test was used to determine the enhancement degree of corrosion resistant ability, the lattice test was used to test the adhesion changes of the paint film after surface treatment, and the acidic zirconium salt spray testing (CASS) was used to analyze the adhesion changes of the new zirconium film after processing. Results The results of auxiliary copper sulfate spot test by adding P2 corrosion inhibitor of zirconium fluid indicated that, the time of the same color change increased 48 s. The oxygen element in the samples which were added P2 corrosion inhibitor of zirconium fluid reduced one time than the original sample. The micelle was identified as oxide micelle, and significantly reduced after treatment by the corrosion inhibitor of zirconium fluid. The lattice test had the equal results, and could pass 480 h CASS. Conclusion of zirconium solution adding P2 corrosion inhibitor treatment can enhance the corrosion resistance of aluminum alloy. The corrosion resistance of aluminum alloy can be enhanced by adding P2 corrosion inhibitor to the zirconium solution. |
