Abstract

The aim of this present work is to study the corrosion behavior of mild steel in aqueous solution containing 60ppm Cl in the presence of TIPA (Triisopropanolamine)-Zn2+ -ST (Sodium Tungstate). Weight loss study has been employed to evaluate the inhibition efficiency of this system. It was found that the inhibition efficiency of TIPA-Zn2+ was improved from 63% to 97% by the addition of 150 ppm of ST. The corrosion rate was calculated in the presence and absence of inhibitor. The protective film consists of Fe2+ -Wo2-, Fe2+ - TIPA complex on anodic site and Zn (OH)2 complex at cathodic site. A mechanism for the inhibition of corrosion is proposed based on the above results. TIPA and Sodium tungstate (Na2WO4) as a corrosion inhibitors of mild steel in aqueous solution containing 60 ppm Cl was investigated by potentiodynamic polarization, and electrochemical impedance spectroscopy (EIS). The surface of the specimen has been examined using, scanning electron microscope
