What is Manganese phosphate coating
Manganese phosphate coating has the highest hardness and superior corrosion and wear resistances of general phosphate coatings. Manganese phosphating is extensively employed to improve the sliding properties of engine, gear, and power transmission systems. The use of manganese phosphated coatings for improved corrosion resistance can be found in virtually all branches of the metal working-industry. Typical examples mentioned here include motor vehicle components in brake and clutch assemblies, engine components, leaf or coil springs, drill bits, screws, nuts and bolts,Read More …
What is Phosphate coatings
Phosphate coatings are used to increase corrosion resistance and improve powder paint adhesion,and are used on steel parts for corrosion resistance, lubricity, or as a foundation for subsequent coatings or painting.It serves as a conversion coating in which a dilute solution of phosphoric acid and phosphate salts is applied via spraying or immersion and chemically reacts with the surface of the part being coated to form a layer of insoluble, crystalline phosphates.Phosphate conversion coatings can also be used on aluminium,Read More …
