Title: Effect of phosphoric acid concentration on corrosion of Cr–Mn–N and Cr–Ni stainless steels
Keywords: Stainless steel, Nitrogen, Phosphoric acid, Polarisation, XPS
Abstract: Phosphoric acid concentration (5–85%) effects on the corrosion behaviour of austenitic Fe–18Cr–12Mn–N steel have been studied by potentiodynamic polarisation measurements. After the anodic polarisation, both the film composition and the electronic structure have been investigated by X-ray photoelectron spectroscopy. The specimen surface examinations have been carried out by scanning electron microscopy. The results of the corrosion behaviour of the steel at issue have been compared to those relevant to two trademark materials [austenitic stainless steels AISI 304 (Fe–18Cr–9Ni) and X14AC15 (Fe–14Cr–15Mn–N)] and developed under the same test conditions.
