    • Zinc and Manganese Phosphating

    MIL-DTL-16232, Type Z or DOD-P-16232, Type M

    Phosphating is a surface treatment which prepares the surface of certain metals, such as steel, using solutions containing mainly phosphoric acid and/or phosphates. This treatment is carried out by immersing the workpiece in an acid bath containing phosphate ions and manganese ions.  

    This process is a chemical reaction in which a phosphorus-containing agent forms a metal phosphate layer on the metal to be treated. This iron phosphate layer is impermeable and provides passivation, improving the corrosion resistance of paint coatings.

    Main uses

    • Phosphating is widely used in the automotive sector.

    Types of treatable metals

    • Steel

    Advantages and benefits

    • Increasing resistance to corrosion and wear, and forming a good base for parts to be painted.
