在镀锌板磷化液基础配方中加入不同的金属离子,研究其对磷化膜的影响。结果表明,金属离子对磷化膜耐硫酸铜点滴时间影响较大;对磷化膜的形貌影响也比较大;在所加入的金属离子中,含Cu2+的磷化膜附着力比含Mn2+、Ni2+的更好。
Different metal ions were added into the basic formula of phosphating solution of galvanized steel to study its influence on phosphating film. The results showed that the metal ions had a significant effect on the dripping time of the phosphating film against the copper sulfate and the influence on the morphology of the phosphating film. In the added metal ions, the adhesion of the phosphating film containing Cu2 + Ni2 + better.
