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).
