Titre : 4-Chloro-benzoic acid [1,2,4]triazol-1-ylmethyl ester as an effective inhibitor of mild steel corrosion in HCl solution Type de document : texte imprimé Auteurs : Z. Tao, Auteur ; S. Zhang, Auteur ; W. Li, Auteur Année de publication : 2011 Article en page(s) : pp. 877–884 Note générale : Génie mécanique Langues : Anglais (eng) Mots-clés : Corrosion inhibition corrosion test electrochemical techniques electron microscopy Résumé : 4-Chloro-benzoic acid [1,2,4]triazol-1-ylmethyl ester (CBT) was synthesized and its inhibiting action on the corrosion of mild steel in 1 M hydrochloric acid solutions was investigated by means of weight loss, potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), and scanning electron microscope (SEM). The results showed that CBT is an excellent inhibitor for mild steel in acid medium and its inhibition efficiency (IE%) is up to 90.2% at a concentration of 10−3 M at 298 K. EIS showed that the charge transfer controls the corrosion process in the uninhibited and inhibited solutions. Potentiodynamic polarization studies clearly reveal that CBT acts essentially as mixed-type inhibitor. Thermodynamic parameters such as adsorption heat (), adsorption entropy (), and adsorption free energy En ligne : http://onlinelibrary.wiley.com/doi/10.1002/maco.200905291/abstract

Titre : Experimental and quantum chemical studies on two triazole derivatives as corrosion inhibitors for mild steel in acid media Type de document : texte imprimé Auteurs : W. Li, Auteur ; L. Hu, Auteur ; Z. Tao, Auteur Année de publication : 2012 Article en page(s) : pp. 1042–1050 Note générale : Génie Mécanique Langues : Anglais (eng) Mots-clés : Ab initio calculations Corrosion inhibition mild steel Surface properties Triazole derivative Index. décimale : 620.1 Essais des matériaux. Défauts des matériaux. Protection des matériaux Résumé : Two triazole derivatives [1-phenyl-2-(5-(1,2,4) triazol-1-ylmethyl-(1,3,4) oxadizaol-2-ylsulphanyl)-ethanone (PTOE) and 2-(4-tert-butyl-benzylsulphanyl)-5-(1,2,4) triazol-1-ylmethyl-(1,3,4) oxadiazole (TBTO)] were synthesized as new corrosion inhibitors for the corrosion of mild steel in 1 M hydrochloric acid solutions. The inhibiting efficiency of the different inhibitors was evaluated by means of weight loss and electrochemical techniques such as electrochemical impedance spectroscopy (EIS) and polarization curves. The electrochemical investigation results indicate that these compounds act as mixed-type inhibitors retarding the anodic and cathodic corrosion reactions and do not change the mechanism of either hydrogen evolution reaction or mild steel dissolution. The studied compounds followed the Langmuir adsorption isotherm, and the thermodynamic parameters were determined and discussed. The effect of molecular structure on the inhibition efficiency has been investigated with ab initio calculations. The electronic properties such as highest occupied molecular orbital (HOMO) energy level, lowest unoccupied molecular orbital (LUMO) energy level, dipole moment (µ) and molecular orbital densities were calculated.
