-Abstract
The corrosion inhibition of carbon steel in 1.0 M HCl using the Aloes leaves extract has been studied. Three electrochemical different techniques have been utilized for studying the corrosion inhibition efficiency behavior of Aloe vera Gel as green corrosion inhibitor in addition to Scanning electron microscopy- Energy dispersive X-ray analysis (SEM-EDX) technique. The four techniques which are potentiodynamic polarization, Electrochemical impedance spectroscopy (EIS), Electrochemical frequency modulation (EFM) and SEM-EDX were used for evaluation at room temperature 25 ᵒC. The results show a good efficiency with low concentration of inhibitor, where the electrochemical methods show that 52 % efficiency with low concentration 100 ppm, in addition to surface morphology of carbon steel show a protected surface compared with noninhibited specimen due to formation of inhibitor layers on surface. EDX show that more concentration of chemical elements of gel extract chemical components adsorbed on inhibited specimen compared with non-inhibited specimen. The inhibition efficiency increases with the increasing of the aloe vera gel concentration.
