CT-16 Black Manganese Phosphate Coating

Description

Black Manganese Phosphate is a friction reducing, corrosion resistant coating. Phosphate produces a fine, dense crystalline coating on ferrous metal substrates. This reduces wear and facilitates break-in of bearing surfaces. Black Manganese Phosphate can be applied to virtually any ferrous metal component (sub-sea parts, tubular goods, threaded components, valves, fasteners, connectors, etc.). Coating weight is 2000 to 3500 mg/ft² depending on composition and hardness of the material being treated and on concentration, time, and temperature of application. Black Manganese Phosphate is especially effective where it is desirable to reduce friction, galling, and scoring on ferrous compounds.

Meets MIL-DTL-16232 Type M, Class 3

Process

Black Manganese Phosphate is applied via immersion in a concentrated, heated bath. The surface of the metal is chemically converted to an integral protective layer of insoluble phosphate crystals. Some components and/or materials may require blasting with abrasive media to provide uniform coating thickness and appearance.

Advantages

Friction reducing, Reduced light reflection, Good appearance, Improved corrosion resistance properties, Reduced running-in wear of sliding parts, Optimum torque-tension requirements, Base or ground coat for dry film lubricants providing excellent anchor properties, Lubrication during cold forming, Components may be oiled for supplemental corrosion resistant properties.
