Phosphating provides an inert, uniform surface texture which acts as an excellent adhesion surface for further treatments, such as painting to a piece and helps to reduce the risk of a number of types of corrosion. It is the treatment of iron or steel by immersion in a dilute solution of phosphoric acid and other additives, which builds up a layer of insoluble phosphate crystals, the type of crystalline depends on the metal mixed with the phosphoric acid.
Manganese phosphating is generally used for engineering components that require break-in wear. The manganese solution provides a thick coating which is excellent for components that work under heavy loads, and it has a higher wear resistance than other phosphate coatings.
Manganese phosphate coating has a great retention for oils and lubricants.
There are many industries that require the use of manganese phosphating including:
Gear and Bearing manufacturers
Heavy equipment manufacturers
Aerospace Industries
Nuclear component fabricators
Cold-forming industries
