MANGANESE PHOSPHATE COATING

Manganese phosphate coatings, also known as Parco Lubrite or Parkerizing, are applied to the surface of ferrous substrates to prevent galling and to improve break-in properties. The coating is formed via immersion in a dilute phosphoric acid solution and is dark grey in appearance. In applications such as firearms, the coating resists scuffing and allows for oil application and reapplication. Uses for manganese phosphate include the production of bearings, bushings, fasteners and other common industrial products. Manganese phosphate is especially useful for projects that require sliding of parts, such as automotive engines and transmission systems.
