| 摘 要： | 用正交试验法优选了磷化配方，通过金相显微镜观察优化后的磷化膜，其金相结构致密、连续.电化学方法测试成膜过程，其极化曲线表明，磷化成膜后，腐蚀电流基本保持不变.利用X射线光电子能谱(XPS)测定膜表面的元素组成，由Zn、Fe、P的不同峰值的能谱、O的能谱峰及俄歇能谱同时存在，可说明磷化膜主要是由Fe及Zn的多种磷酸盐构成.同时，技术性能测试表明，该磷化液溶液稳定、沉渣少、成膜速度快且磷化膜耐蚀性能好.

| Abstract: | An optimal bath composition of phosphating for steel at ambient temperatures is obtained by orthogonal trial tests.Metallographic observation reveals that the phosphating coating is compact and continuous.The forming process of phosphating coatings was studied by electrochemical method.The dynamic polarization curves indicated that the corrosion-current keeps nearly not change after the coating formation.The chemical composition of the formed coating was investigated by X-ray photoelectron spectroscopy(XPS).It showed that phosphating coating may be made of phosphates of Fe and Zn because there are some obvious peaks of Zn,Fe,P elements and different spectrographic peak of O.At the same time,it was shown that this phosphating bath is stable,less sludge and higher film-formation rate.The phosphating coating formed with this bath has good corrosion-resistance. |
