Abstract :
The application of Nigella sativa oil extract (NS) as a corrosion inhibitor for mild steel (MS) protection was investigated in neutral solution of 3% NaCl solution has been investigated byusingweight loss method, potentiodynamic polarizationand electrochemical impedance spectroscopy (EIS). Polarization curves indicate that NS is a cathodic inhibitor. The inhibition efficiency of NS reached 94% at 250 ppm. However, the adsorption of thisinhibitor at the metallic surface is a physisorption type and follows the Langmuir isotherm adsorption. Thus the thermodynamic and kinetic parameters were calculated and discussed
