WebThe phosphating process is pretty common for equipment parts that are made of steel because the iron in the steel is necessary for the coating to form. When resistance to wear and galling is required, manganese phosphate coating is the right coating to apply. There are different phosphate coatings available and manganese coating is the hardest. WebThe soluble phosphate becomes insoluble in the rising pH region and phosphate coating begins to form as a result of crystallization. 3Zn +2 + 6H 2 PO 4- → Zn 3 (PO 4) 2 + 4H + + 4H 2 PO 4- This etching and coating process continues until the entire surface is covered with a phosphate layer.
