Influence of corrosion on the interface between zinc phosphate steel fiber and cement / M. Sun in Materials and corrosion, Vol. 63 N° 1 (Janvier 2012) 

Public ISBD [article]  in Materials and corrosion > Vol. 63 N° 1 (Janvier 2012) . - pp. 67–72 Titre : Influence of corrosion on the interface between zinc phosphate steel fiber and cement Type de document : texte imprimé Auteurs : M. Sun, Auteur ; D.-J. Wen, Auteur ; H.-W. Wang, Auteur Année de publication : 2012 Article en page(s) : pp. 67–72 Note générale : Génie Mécanique Langues : Anglais (eng) Mots-clés : Corrosion  Interface  bond  Steel  fiber  Zinc  phosphate Résumé : The interface bond between steel fibers and concrete matrix is a key factor influencing bearing capacity of steel fiber reinforced concrete (SFRC). In order to improve the interface bond strength and corrosion resistance, a kind of method was put forward by depositing zinc phosphate (ZnPh) coating on steel fiber surface in this paper. The corrosion behavior was investigated in 5% NaCl solution by using linear polarization measurement. Microstructure analysis (SEM and EDX) and fiber pull-out test in combination with linear polarization measurement were carried out. The results prove that ZnPh coatings fabricated on the carbon steel surface can not only protect steel fiber against corrosion, but also enhance the mechanical interlocking bonds between fibers and matrix.
