Manganese Phosphating

Manganese phosphate coatings used for corrosion protection, anti-galling and lubricity. Of the numerous phosphate coating available, manganese phosphate coatings are the hardest, while providing unbeatable corrosion and abrasion protection. Typically applied to components manufactured from mild steel or cast-iron substrates, manganese phosphate provides a long-wearing crystalline absorptive coating. In comparison to zinc phosphate coatings, manganese phosphate coatings offer continued wear protection after the breaking in of components that are subject to wearing. These coatings are applied only by immersion. Uses for manganese phosphate applications include the production of oil field and marine glands, bearings, bushings, fasteners, and other common industrial products. Manganese phosphate coating is especially useful in projects that require sliding of parts, such as automotive engines and transmission systems.
