Influence of tensile stress on corrosion behaviour of high-strength galvanized steel bridge wires in simulated acid rain / W. J. Yang in Materials and corrosion, Vol. 63 N° 5 (Mai 2012) 

Public ISBD [article]  in Materials and corrosion > Vol. 63 N° 5 (Mai 2012) . - pp. 401–407 Titre : Influence of tensile stress on corrosion behaviour of high-strength galvanized steel bridge wires in simulated acid rain Type de document : texte imprimé Auteurs : W. J. Yang, Auteur ; P. Yang, Auteur ; X. M. Li, Auteur Année de publication : 2012 Article en page(s) : pp. 401–407 Note générale : Génie mécanique Langues : Anglais (eng) Mots-clés : Corrosion;  Galvanized  steel  wire;  Simulated  acid  rain;  Tensile  stress Résumé : Corrosion behaviour of the high-strength galvanized steel wires under tensile stress was researched by electrochemical polarization and salt spray test (SST) using simulated acid rain as electrolyte. Electrochemical polarization and SST results showed corrosion rate rose significantly with increasing tensile stress; white grains were observed by SEM after polarization, while cellular and dendritic crystals appeared on the rust layer after SST. XRD and TG-DTA results revealed (Zn(OH)2)3 · ZnSO4 · 5H2O was the main corrosion product, and traces of Fe2(SO4)2O · 7H2O, Fe2(SO4)3, Fe2O3 · H2O were also detected. A three-stage corrosion process for the galvanized steel wires during SST was proposed.
