This specification covers the requirements for a manganese phosphate coating on ferrous alloys. This process has been used typically to produce a coating that will minimize chafing of contacting steel surfaces and retain an oil film, but usage is not limited to such applications. While the materials, methods, applications, and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address the hazards that may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved.
