Effect of glycine on the electrochemical and stress corrosion cracking behavior of Cu10Ni alloy in sulfide polluted salt water / Ahmed Abdel Nazeer in Industrial & engineering chemistry research, Vol. 50 N° 14 (Juillet 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 14 (Juillet 2011) . - pp. 8796–8802 Titre : Effect of glycine on the electrochemical and stress corrosion cracking behavior of Cu10Ni alloy in sulfide polluted salt water Type de document : texte imprimé Auteurs : Ahmed Abdel Nazeer, Auteur ; Nageh K. Allam, Auteur ; Gehan I. Youssef, Auteur Année de publication : 2011 Article en page(s) : pp. 8796–8802 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Glycine  Electrochemical  Corrosion  cracking Résumé : Corrosion is a natural and inevitable problem that is still a challenge in materials design, with regard to achieving greater operational efficiency. In this study, the electrochemical and stress corrosion cracking (SCC) behavior of Cu10Ni alloy in a 3.5% NaCl solution in the presence of different concentrations of sulfide ions were studied. The presence of sulfide ions has been shown to increase the susceptibility of the material to SCC at different strain rates. The addition of glycine (gly) to the test electrolyte increased the time to failure by changing the mode of failure from brittle transgranular cracking to ductile failure. Therefore, gly can be considered as a potential environmentally friendly corrosion inhibitor. The electrochemical measurements showed that gly acts as a mixed corrosion inhibitor. The synergistic effect of potassium iodide (KI) and gly is also investigated. Electrochemical frequency modulation (EFM) and potentiodynamic polarization data are in good agreement with the SCC results.
