Abstract

‎This work aumis to study the inhibitory efficacy of the extract of the Alandad‏ ‎plant on the cossosion of stecl XC52 in an acidic meduim (sulfuric acid 1 molar)‏ ‎using the method of wcight loss and comparaison of previous studies of the‏ ‎electrochemical method ( polarization curves}. The results obtained by the‏ ‎classic method (wcight loss) showcd that this extract has an important inhibitory‏ ‎efficacy of more than 90% and the comparison. Showed that the yield of‏ ‎inhibition was high. And the adsorption curves of Langumair and Tamkcen‏ ‎prove that this extract has adsorption the surface of the mineral
