Phosphating is the process of converting a steel surface to iron phosphate. This is mostly used as a pretreatment method in conjunction with another method of corrosion protection. A layer of phosphate coating typically includes iron, zinc or manganese crystals. Phosphate coatings are usually applied to carbon steel, low-alloy steel and cast iron.
We use iron phosphate to offer moderate corrosion protection. It also serves as a primer for additional coatings. Zinc Phosphating: The zinc phosphating process provides a thicker coating than iron phosphating. This results in a better adhesion of paint and enhanced corrosion resistance. The automotive and military industries use this process.
