Effect of sodium silicate pretreatment on phosphate layer: Morphology and corrosion resistance behavior / J. Wang in Materials and corrosion, Vol. 63 N° 4 (Avril 2012) 

Public ISBD [article]  in Materials and corrosion > Vol. 63 N° 4 (Avril 2012) . - pp. 317–322 Titre : Effect of sodium silicate pretreatment on phosphate layer: Morphology and corrosion resistance behavior Type de document : texte imprimé Auteurs : J. Wang, Auteur ; W. Zhou, Auteur ; Y. Du, Auteur Année de publication : 2012 Article en page(s) : pp. 317–322 Note générale : Génie mécanique Langues : Anglais (eng) Mots-clés : Phosphating;  pretreatment;  sodium  silicate Résumé : Phosphating is a widely adopted treatment in industry for many purposes. In this paper, carbon steel was pretreated with sodium silicate before phosphating. X-ray diffraction (XRD), scanning electron microscopy (SEM), and electrochemical measurements were used to evaluate the pretreatment effect by sodium silicate on the phosphating layer. The results demonstrate that the phosphate layer pretreated by sodium silicate has a better corrosion resistance as compared with the un-pretreated ones. More compact and uniform coatings composed of finer crystals were obtained with the pretreatment of sodium silicate.
