Iron phosphate bath
The process takes advantage of the low solubility of phosphates at medium or high pH. The bath is a solution of phosphoric acid (H3PO4), containing the desired iron, zinc or manganese cations and other additives. The acid reacts with the iron metal producing hydrogen and iron cations: Fe + 2 H 3O → Fe + H 2 + 2 H 2O The reaction consuming protons raises the pH of the solution in the immediate vicinity of the sur… WebJun 6, 2024 · Iron Phosphate Iron Phosphating increases paint adherence and impact resistance as well as protects against oxidation.
