Abstract
In this study, plant extract (wild clary) are tested and applied to steel (AISI l015) to prevent its corrosion in two mediums of sea water and 0.5 M HCl using electrochemical studies at three temperatures (298, 318, 338 K) by adding five concentrations of the extract (5, 10, 15, 20, 25) mL /L. The inhibition efficiency was found to be excellent, reaching 83.078% at a concentration of 20 (ml/L) and a temperature of 298 (K), which is the best concentration in seawater, and 92.944% at a concentration of 25 (ml/L) and a temperature of 298 (K) which is the best concentration in an acid medium hydrochloric.
The discussion of the dissertation was conducted in a scientific atmosphere and a master's degree with grade of pass was awarded to the student after the completion of all the corrections that have been decided by the examiners.
