    OverviewProcessUsesSee alsoFurther reading

    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(H3O ) ions, raising the pH, and causing the dissolved salt to fall out of solution and be precipitated on the surface. The acid and m
