摘要:
以改善 30CrMnSi 钢中温磷化膜性能为目的,开发了基于氟化镍为促进剂的中温磷化配方。利用开路电位 - 时间( E-t )曲线研究了氟化镍的促进作用,利用单因素实验考察了柠檬酸和磷化时间对磷化膜性能的影响,通过正交试验优化了磷酸二氢锌、硝酸锌、磷酸、氟化镍的含量。结果表明:当氟化镍含量达到 0.8 g/L 时,促进了磷化膜的生长过程,磷化反应效果明显; 单因素实验和正交试验优化的磷化配方为磷酸二氢锌 30 g/L 、硝酸锌 80 g/L 、磷酸 8 g/L 、氟化镍 2 g/L 、柠檬酸添加量为 1.2 g/L ,在 60 ℃ 下磷化 6~10 min 。
Abstract:
: To improve the performance of the middle-temperature phosphating film of 30CrMnSi steel , a middle-temperature phosphating formula based on nickel fluoride as an accelerator was developed. The promotion effect of nickel fluoride was studied by open circuit potential-time ( E - t ) curve. The effects of citric acid and phosphating time on the properties of phosphating films were investigated by single-factor experiment. The contents of zinc dihydrogen phosphate , zinc nitrate , phosphoric acid and nickel fluoride were optimized by orthogonal experiment. Experiment results showed that when the content of nickel fluoride reached 0.8 g/L , the growth process of phosphating film was promoted , and the phosphating reaction effect was obvious. The optimum phosphating formula was zinc dihydrogen phosphate 30 g/L , zinc nitrate 80 g/L , phosphoric acid 8 g/L , nickel fluoride 2 g/L , citric acid 1.2 g/L , phosphating at 60 ℃ for 6-10 min.
