Phosphate conversion of metals

Industrial and decorative phosphate conversion coatings

Phosphate conversion is a common process used on iron and ferrous alloys. Phosphate conversion alters the surface of the metal by creating phosphate crystals; this improves resistance to corrosion by forming a base for the application of paint.

Industrial phosphating

Industrial phosphating is a specific process where objects are immersed in a bath of phosphate and phosphoric acid, which causes a chemical reaction on the surface of the metal.

Decorative phosphating

Decorative phosphating imparts anti-rust and anti-seizing properties; the coating only achieves its ideal anti-corrosive properties after immersion in the appropriate protective oils.
