按照该方法生成的磷化膜不仅具有很好的耐强碱介质性能,又可承受热负荷作用。本方法涉及的磷化液其沉渣极少。这种磷化法特别适用于阴极电泳涂漆前的金属表面处
The phosphating film generated according to the method not only has good resistance to alkali-resistant media, but also withstands heat load. The phosphating solution of the method has very few sediments. This method of phosphating is particularly suitable for cathodic electrophoretic coating of metal surfaces
