  • Abstract
    The essential oil of Lavandula intermedia Walberton's Silver Edge (LAV) has been studied as a carbon steel corrosion inhibitor in 1 M hydrochloric acid using electrochemical obstacle spectroscopy (EIS), Tafel's polarization methods. The effect of extract concentration of (LAV) and immersion time on inhibition efficacy were studied. The effect of immersion time on the effectiveness of steel corrosion inhibition in 1M HCl was also studied in the 0.5 – 12 hour time interval. The results revealed that the essential oil of (LAV) tested reduces the kinetic process of the corrosion process of steel in medium 1 M HCl. Its efficiency increases with concentration and reaches a maximum value of 84% to 1% of LAVs. This corrosion inhibition effect attributed to was associated with the formation of a protective film provided to the metal surface by the complex chemical constituents of the oil extracted from (LAV), which is confirmed by surface analysis by scanning electron microscopy spectroscopy (SEM).
