| 摘 要： | 常温磷化无毒、节能,但成膜速度慢,且膜的耐蚀性能差。为此,在传统的常温磷化液中加入3种促进剂,运用扫描电镜、退膜法、硫酸铜点滴试验、电化学测试等手段,对磷化膜表面形貌、膜重、耐蚀性能等进行了测量,研究了3种促进剂在常温磷化中的促进作用及机理,分析促进剂之间的协同效应,优选出加速效果比亚硝酸盐更好的复合促进剂(1.0g/L氯酸钠,0.5g/L3-硝基苯磺酸钠,1.0g/L硫酸羟胺)。结果表明:3种促进剂在常温下均能促进磷化膜形成,但促进机理不同;优选复合促进剂具有很好的协同效应,能加快成膜速度,形成均匀、致密、耐蚀性优良的磷化膜,且磷化过程不会分解出有毒气体NOX,完全可以取代亚硝酸盐。

| Abstract: | Three kinds of accelerators were introduced into conventional room-temperature phosphating fluids.The effect of the accelerators on the morphol-ogy,mass and corrosion resistance of the phosphating films was analyzed by observation with a scanning electron microscope andby conducting film-releasing tests,copper sulfate dropping tests and electrochemical tests.The accelerating performance and mechanism as well as synergistic effect of the accelerators were investigated,and the optimized composition of the com... |
