Phosphate Coating & The Phosphating Process
Phosphate coatings are a crystalline conversion coating for steel and other metals that is formed on a ferrous metal substrate. The process of
Phosphate coating is employed for the purpose of pretreatment prior to coating or painting,
increasing corrosion protection and improving friction properties of sliding components. In other instances, phosphate coatings are applied to threaded parts and top coated with oil (P&O) to add anti-galling and rust inhibiting characteristics.
The
phosphating process relies on the basic pickling reaction that occurs on the metal substrate when the process solution comes in contact with the metal. The main benefits that phosphating provides is strong adhesion and corrosion protection. Typically, phosphate coatings used on steel parts but can also be used on aluminum. Metal coatings offers both zinc phosphate and manganese phosphate coating. Our phosphate coatings additionally are offered in both dark gray & black.
