Application of new azomethine as corrosion inhibitor on mild steel in acidic medium: Electrochemical, thermodynamic and SEM investigations.
1-(4-Nitrphenylo-imino) -1 (phenylhydrazono) - propan-2-one (NOAM) was studied as a corrosion inhibitor for the protection of mild steel in 1 M HCl solution by means of weight loss, polarization and electrochemical impedance spectroscopy. The inhibition efficiency was found to increase with... Voir les détails
