Abstract
The corrosion inhibition effectiveness of Aizoon canariense for carbon steel (CS) in 2 M HCl (the corrosive medium) has been examined by employing chemical and electrochemical methods. The inhibition efficiency was found to improve with a rise in the environment's extract and temperature concentration. The inhibitive effect of this extract was explained on the basis of adsorption on the metal surface; the adsorption effect follows Langmuir adsorption isotherm. The percent inhibition efficiency (IE%) reached 90.23% at 45oC, and activation energy (E*a) has been determined in the presence and absence of Aizoon canariense extract. The corrosion rate was calculated and revealed that Aizoon canariense has a good inhibition effect on CS. The surface morphology of CS was examined by employing various techniques. The polarization results indicated that this extract acts as a mixed kind inhibitor. The parameters for the corrosion procedure have also been determined and discussed.
