An Eco-friendly Corrosion Inhibitor: Neolamarckia cadamba Leaves Extracts for SS 304 in 1 M HCl Solution

Neolamarckia Cadamba leaf extract as a green and environment-friendly inhibitor for the protection of stainless steel (SS) 304 from corrosion in 1 M HCl solution. The inhibition effect of NC inhibitor was measured by different electrochemical methods for example Weight loss measurement, SEM-scanning electron microscopy, PDP-potentiodynamic polarization, and EIS-electrochemical impedance spectroscopy used for the inhibition effects studies. Using Langmuir adsorption isotherm, we studied the adsorption of the extracts of leaves. All of the methods used indicate a productive result on inhibition efficiency with a concentration of natural inhibitor increasing.
