Cephamycin; a novel corrosion inhibitor for mild steel corrosion in hcl acid solution

Abstract

The corrosion inhibition properties of cephamycin (CFC) for mild steel corrosion in HCl solution were analysed by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization methods. Potentiodynamic polarization study clearly revealed that cephamycin acted as mixed type inhibitor. The experimental data showed a frequency distribution and therefore a modelling element with frequency dispersion behaviour, a constant phase element (CPE) has been used. © 2013 by ESG.
