Etude de l’inhibition de la corrosion de l’acier X60 en milieux acides HCl par l’huile essentielle de romarin.

Abstract

In the present work, we have set ourselves to follow the study, using gravimetric techniques, of the corrosion inhibition of X60 steel by the essential oil of rosemary in HCl 1M . The results of mass loss has a good agreement.. The results obtained showed that the rate of corrosion decreases as a function of the increase in the concentration of the added oil and stabilizes from a value of 1.5 g / l of rosemary oil. To this effect the corrosion inhibitory efficacy reaches a maximum value of about 81.197% after the addition of rosemary oil after a tim = 24 h.
