Abstract

The corrosion inhibition of galvanized steel (GI steel)sheets  in 5% NaCl with Esomeprazole (EPZ) as green inhibitor has been reported  by Mass  loss, Potentiodynamic  polarization, electrochemical impedance spectroscopy ,  hydrogen permeation and quantum mechanical  studies. All these techniques reveal that the EPZinhibits the corrosion of galvanized steel in 5% NaCl medium.Polarization studies indicated that inhibitors are acted as mixed type inhibitor. The adsorption of the compounds on galvanized steel surface follows Langmuir adsorption isotherm.
