Title: NATURAL INHIBITOR OF CORROSION OF ALUMINIUM ALLOY EN AW-2011 IN ACIDIC ENVIRONMENT
Keywords: corrosion inhibition, aluminum alloy, Lavender essential oil

Abstract: Lavender essential oil was used as a natural corrosion inhibitor for the aluminum alloy EN AW-2011 in 1M H2SO4 and 1M HCl. A gravimetric and electrochemical studies were carried out to determine the inhibitory effect of the of Lavender oil. The results from the gravimetric test show that the optimum of the inhibitory effect of the Lavender oil in 1M H2SO4 is 85.3%, while in 1M HCl it is only 47.8 %. As the concentration of Lavender oil increases, its inhibitory effect in both acids increases. Lavender essential oil is a better natural corrosion inhibitor for EN AW-2011 alloy in 1M H2SO4 than it is when the alloy is immersed in 1M HCl.
