N2 - A corrosion inhibition study of mild steel in 1 M sulfamic acid was conducted using grape seed extract (GSE) as a possible green inhibitor. Electrochemical techniques were adopted to measure the corrosion rate in both the absence and presence of the GSE. Conditions were standardized to obtain optimum inhibition efficiency by varying the concentration of inhibitor and temperature. The kinetic parameters were calculated using the Arrhenius equation. Surface analysis was conducted by scanning electron microscope (SEM) and atomic force microscope (AFM) techniques. A suitable mechanism was proposed for the corrosion inhibition process. Grape seed extract showed a maximum efficiency of 65%, with a concentration of 0.24 g/L at 303 K from potentiodynamic polarization (PDP) studies. With the increase in temperature, the efficiency decreased, resulting in the GSE inhibitor’s physical adsorption. Surface morphology studies supported the adsorption of GSE on mild steel. GSE acted as an efficient green inhibitor with environmental benefits.
