Phosphating

Phosphating is a chemical surface treatment method in which a metallic surface reacts with an aqueous phosphate solution. Phosphating is a type of conversion coating applied to steel and iron components. It is often utilized as a pre-treatment step before providing corrosion protection.
Phosphate coatings are usually applied to carbon steel, low-alloy steel and cast iron. The coating is formed with a solution of iron, zinc or manganese phosphate salts in phosphoric acid, and is applied by immersing the substrate into the solution.

There are three common types of phosphating:
Manganese Phosphating
Zinc Phosphating
Iron Phosphating
Advantages of Phosphating:
Typical Application for Phosphating:
Phosphating is commonly used on steel and iron components, but can also be applied to elements made of zinc or other non-ferrous metals. It offers benefits such as corrosion protection, reduced wear, improved adhesion, and electrical insulation. Since the phosphate layer produces adheres very well, it is often used as a substrate for coatings.
