  • What is a Phosphating? Definition from Corrosionpedia

    What Does Phosphating Mean? Phosphating is a conversion coating that is applied to steel or iron components, and is mostly used as a pretreatment method in conjunction with another method of corrosion protection The process involves immersing a component in a dilute solution, which then converts the surface of the metal into a layer of microscopic phosphate crystals
