WebThe bath is a solution of phosphoric acid (H 3 PO 4), containing the desired iron, zinc or manganese cations and other additives. The acid reacts with the iron metal producing hydrogen and iron cations: ... The acid and metal reaction also creates iron phosphate locally which may also be deposited. WebThe adsorption of CSE on metal surface obeyed Langmuir adsorption isotherm. Polarization measurements showed that the CSE acted as mixed inhibitor in 0.5 M and 2.0 M phosphoric acid solution and the inhibitor molecules followed physical adsorption on …
WebThe treatment of metal surfaces with phosphoric acid or phosphate salts to provide a coating of insoluble metal phosphate crystals is referred to as phosphating. These … WebPhosphates – Metal Finishing. Phosphoric acid-based chemical polishes are used primarily to chemically polish (brighten) aluminum and aluminum alloys. These products, which can be tailored for a specific alloy, work in conjunction with nitric acid to smooth the surface of aluminum parts, giving a bright appearance.

For example, you form Fe 2 O 3 on Fe (when talking about iron or steel). Acid can dissolve the rust (Fe 2 O 3 ). However, the acid will also oxidize the metal further, forming more rust, and dissolving that rust.
