在5．0g／LZn2+的锌系磷化液中，分别以磷化过程中的折气量、膜重、膜的耐蚀性能作为考核指标，对[PO43-]／[NO3-]、[Ni2+]、pH值的影响进行了综合研究。结果表明，上述三种因素对中温磷化的良好膜层有着关键性的作用。此外，还就三种因素对磷化结晶过程的影响及膜的形貌作了探讨。
The content of [PO43] / [NO3 -], [Ni2 +] in the 5.0g / L Zn2 + zinc phosphating solution was determined by the amount of gas blown, the weight of the membrane and the corrosion resistance of the membrane. , PH value of a comprehensive study. The results show that the above three factors play a key role in the good film of moderate temperature phosphating. In addition, the influence of three factors on the phosphating crystallization process and the morphology of the membrane were also discussed.
