Abstract

The anticorrosive effects of Leek seeds aqueous extract (LSAE), Allium ampeloprasumvar.kurrat, on Al 6061, Al 7075, and Al 2024 in seawater was investigated using weight loss (WL) measurements and potentiodynamic polarization (PDP) technique.The effectiveness of the inhibitor was studied as a function of temperature using PDP technique. The results showed that LSAE can work as effective corrosion inhibitor and inhibition efficiencies increased with the increase of LSAE concentration. The inhibition efficiency of Al 6061 improved with an increase in temperature, whereas the inhibition efficiency of Al7075 and Al 2024 was decreased with an increase in temperature. Adsorption of organic molecules on alloys surfaces was emphasized by energy-dispersive X-ray spectroscopy (EDS). Temkin Adsorption isotherm was found to be the best fit for the experimental polarization data and adsorption strengths of the LSAE molecules on the studied alloys surfaces increased as follows: Al 6061 > Al7075 > Al 2024.
