摘　　要：　为提高热镀锌钢板的耐蚀性,对热镀锌钢板铬酸盐钝化工艺进行了研究。采用盐雾试验、钝化膜的微观形貌等手段分析了钝化液浓度及钝化工艺参数(钝化液温度、烘干时间、烘干温度等)对热镀锌钢板铬酸盐钝化膜耐蚀性的影响。结果表明,采用试验确定的钝化工艺处理得到的钝化膜耐蚀性明显提高,对实际生产具有较好的指导意义。In order to improve the corrosion resistance, the passivation process of hot-dipped galvanized steel has been studied. Influences of the passivation liquid concentration and passivation parameters (passive temperature, drying time, drying temperature etc.) on the corrosion resistance of passivation film of hot-dipped galvanized steel were analyzed by the salt spraying experiment and the microstructures of passivation film. The results showed that the corrosion resistance of passivation film obtained under the determined passivation process had been improved. It's very useful for the actual production.
