What is Phosphating? Definition from Corrosionpedia

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. Phosphating is also known as phophatizing and phosphate conversion coating.
