摘要:
以耐硫酸铜点滴时间作为评判冷轧汽车板锌系磷化膜耐腐蚀性能的依据，通过单独分析表调液温度、表调液浓度和表调时间对耐硫酸铜点滴时间的影响，得到最佳表调工艺条件为：表调液温度30 ℃、表调液浓度4 g/L、表调时间35 s。结果表明：在最佳表调工艺条件下的磷化膜耐硫酸铜点滴时间达到185 s，较未表调处理的磷化膜耐硫酸铜点滴时间（142 s）明显延长。在最佳工艺条件下进行表调处理延长了磷化膜耐盐雾时间，磷化膜表现出较强的耐盐雾腐蚀能力，优于未表调处理的磷化膜。盐雾试验前后，磷化膜的主要成分没有明显变化。
Abstract:
The dropping time was taken as the basis for evaluating the corrosion resistance of zinc phosphating film on cold-rolled automotive sheet. Through analysis of the influence of the temperature of surface conditioning agent, the concentration of surface conditioning agent and surface conditioning time on the dropping time of phosphating film separately, the optimal surface conditioning process conditions were obtained as follows: the temperature of surface conditioning was 30 ℃, the concentration of surface conditioning agent was 4 g/L and the surface conditioning time was 35 s. The results showed that the dropping time of the phosphating film obtained under the optimal surface conditioning process conditions reached 185 s, which was significantly longer than that of the phosphating film obtained without surface conditioning treatment （142 s）. Surface conditioning treatment under the optimal process conditions can prolong the salt spray resistance time of the phosphating film, and the phosphating film showed a great corrosion resistance in salt spray test, which was better than that of the phosphating film without surface conditioning treatment. Before and after salt spray test, there was no significant change in the main components of the phosphating films.
