| Résumé : |
The effect of amino compounds as inhibitors of steel corrosion in hydrochloric 1M. The study was carried out by the method of weight loss and potentiodynamic polarisation curves. The inhibition efficiency increases with the concentration of the inhibitor, achieving 95% of the indole of the concentration 5.10-3M. Exposure measures polarization essentially act as mixed inhibitors. The adsorptions of these inhibitors on the surface of the steel turn out for the isotherm adsorption of Temkin. The values of activation energy and free energy of adsorption of the studied compounds are calculated to study the mechanism of the inhibition of the corrosion. The study temperature indicates an increase in inhibition efficiency with the temperature and the activation energies decreased in the presence of the inhibitor, the temperature range studied is 293 - 313 ° K. finally studied the effect of salts such as (NaCl, Na2SO4, Na3PO4, NaNO3, Na2CrO4) on the effectiveness of the inhibitor. |
