However, the dissolution of iron at the local anode is the decisive factor for the rate of phosphating process, whereby the cathodic processes of the phosphte coating formation are controlled. ... Where Me either Fe, Zn, Zn or Mn.
Manganese(II) phosphate is an inorganic compound with the chemical formula Mn 3 (PO 4) 2.It has industrial importance as a constituent of manganese based phosphate conversion coatings. Formation. Manganese phosphates often combine with iron phosphates through paragenesis. In the process of paragenesis, each mineral affects the manner in which the other is crystallized.
Manganese phosphate may also serve as a base for Teflon, Xylan, powder coating or CARC paint. Manganese phosphate also goes by the trade name Parco Lubrite, is sometimes called parkerizing in reference to finishing on firearms, or may be called phosphatizing. Chem Processing, Inc. offers MIL-DTL-16232 Type M, Class 4 (black) phosphate.
Phosphating. Manganese phosphate coating is the treatment of irons or steels with a dilute solution of phosphoric acid and selected proprietary chemicals which produces a crystalline, oil absorptive coating with excellent wear resistance.
