Corrosion inhibition of mild steel in hydrochloric acid by 6-aminohexanoic acid / M. Abdeli in Materials and corrosion, Vol. 61 N° 2 (Fevrier 2010) 

Public ISBD [article]  in Materials and corrosion > Vol. 61 N° 2 (Fevrier 2010) . - pp. 147–151 Titre : Corrosion inhibition of mild steel in hydrochloric acid by 6-aminohexanoic acid Type de document : texte imprimé Auteurs : M. Abdeli, Auteur ; N. P. Ahmadi, Auteur ; R. A. Khosroshahi, Auteur Année de publication : 2010 Article en page(s) : pp. 147–151 Note générale : Génie mécanique Langues : Anglais (eng) Mots-clés : 6-aminohexanoic  acid;  inhibitor  efficiency;  mild  steel Résumé : The inhibiting behavior of 6-aminohexanoic acid (C6H13NO2) on mild steel corrosion in 1 M HCl as corroding solution at 25 °C was evaluated by weight loss, polarization, and electrochemical impedance spectroscopy (EIS) methods. The weight loss, polarization, and EIS measurements were relatively in good agreement together. Results obtained by the three methods showed that the inhibition efficiency (%IE) increases with increasing the concentration of 6-aminohexanoic acid up to 6.86 × 10−05 M (about %IE = 80). It was also found that the adsorptive behavior of the investigated inhibitor on the steel surface followed Langmuir-type isotherm, the 6-aminohexanoic acid acted as a mixed type inhibitor and its inhibition mechanism obeys from the chemisorption interaction between 6-aminohexanoic acid and the mild steel.
