Phosphating is a chemical process. By immersing the work piece in acidic solutions, the chemical reaction with the base material creates a hard metal phosphate layer bonded to the surface. The layer has a fine crystalline structure and is almost insoluble. Both zinc and magnesium phosphates can be used.




- good temporary corrosion protection

- reduction in abrasion values

- fine crystalline layer formation

- improved sliding properties

- electrically insulating

- eases subsequent reforming

- partial coating possible

- optical improvement of components
