Advantages of phosphating
The high-temperature manganese phosphating film has the characteristics of dense film layer, good wear resistance, and excellent anti-corrosion and anti-rust performance. Because the phosphating film has a large specific surface area and good adsorption capacity, it is widely used as a coating primer. It can not only enhance the bonding force between the base metal and the coating, but also improve the corrosion resistance of the workpiece.
