Phosphating is surface modification of substrate materials before coating with others process. There are many application of Phosphating such as anti – corrosion, based for organic coating, anti-sizer for cold forming and wear resistance.
After surface was cleaning by suitable techniques, metal surface will be reacted with Phosphating chemical and generate an even crystal of the Phosphate compound film.
