Experimental and theoretical study of the inhibition effects of some Schiff bases as corrosion inhibitors of aluminium in HCl / A. Aytaç in Materials and corrosion, Vol. 63 N° 8 (Août 2012) 

Public ISBD [article]  in Materials and corrosion > Vol. 63 N° 8 (Août 2012) . - pp. 729–734 Titre : Experimental and theoretical study of the inhibition effects of some Schiff bases as corrosion inhibitors of aluminium in HCl Type de document : texte imprimé Auteurs : A. Aytaç, Auteur ; S. Bilgiç, Auteur ; G. Gece, Auteur Année de publication : 2013 Article en page(s) : pp. 729–734 Note générale : Génie mécanique Langues : Anglais (eng) Mots-clés : Aluminium;  corrosion  inhibition;  DFT;  impedance;  Schiff  base Résumé : The inhibition efficiencies of two new synthesized Schiff bases have been investigated for aluminium in 0.5 M HCl solution using experimental and theoretical methods. Potentiodynamic polarization and EIS method were used to determine the inhibition efficiencies. From the experimental results it has been found that both compounds adsorb on the aluminium surface according to the Temkin adsorption isotherm. Quantum chemical calculations were further applied to reveal the adsorption structure and explain the experimental results. A good correlation between the quantum chemical parameters and the experimental inhibition efficiency has been found.
