Corrosion is a fundamental process which playsan important role in economics and safety.Apparently, corrosion cannot be avoided, but its severity can beprevented. Inhibitors have always been considered to be the first lineof defense against corrosion. Several corrosioninhibitors are available today. The objective of this study was toevaluate the effectiveness of sodium benzoate as an inhibitorto slow down or prevent corrosion. This project involves theuse of gravimetric measurements, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) to evaluate inhibitive action of sodium benzoate on corrosion behavior ofAA6063 aluminium alloy in seawater. The electrochemical measurements showed that the presence of sodium benzoate as an inhibitor significantly decrease the weight loss, corrosioncurrent densities (icorr), corrosion rates and double layer capacitance (Cd), whilst increasing the polarization resistance (Rp). |
