Phosphate coating is used on steel parts for corrosion resistance, lubrication, or as a foundation for subsequent coatings or painting. It serves as a conversion coating in which a dilute solution of phosphoric acid and phosphate salts is applied via spraying or immersion and chemically reacts with the surface of the part being coated to form a layer of insoluble, crystalline phosphates.
In organic chemistry, phosphate or orthophosphate is an organophosphate, an ester of orthophosphoric acid of the form PO 4 RR′R″ where one or more hydrogen atoms are replaced by organic groups. An example is trimethyl phosphate, (CH 3) 3 PO term also refers to the trivalent functional group OP(O) 3 in such esters.. Orthophosphates are especially important among the various

The main types of phosphates are iron, zinc and manganese. Manganese phosphates are used for corrosion resistance, wear resistance and lubricity. They are applied by an immersion process. Iron phosphate is typically used as a base for further coatings and may be applied via spray or immersion. Zinc phosphate is primarily used for corrosion resistance (Phos Oil), wear resistance, lubricity or
Process. The application of phosphate coatings makes use of phosphoric acid and takes advantage of the low solubility of phosphates in medium or high pH solutions. Iron, zinc or manganese phosphate salts are dissolved in a solution of phosphoric acid. When steel or iron parts are placed in the phosphoric acid, a classic acid and metal reaction takes place which locally depletes the hydronium
