Titre : Characterization of passivated tinplate for food can applications Type de document : texte imprimé Auteurs : N. Mora, Auteur ; E. Cano, Auteur ; J. M. Bastidas, Auteur ; E. Almeida, Auteur ; J. M. Puente, Auteur Année de publication : 2002 Article en page(s) : p. 53-58 Note générale : Bibliogr. Langues : Américain (ame) Tags : Application Caractérisation 'Composition chimique' Morphologie Sodium Dichromate Passivation 'Fer blanc' Boîte 'Industrie alimentaire' Index. décimale : 667.9 Revêtements et enduits Résumé : Tinplate specimens for food can applications, passivated by cathodic treatment in a sodium dichromate solution, were studied. Three experimental methods: coulometric, spectrophotometric, and atomic absorption spectrophotometry (AAS), were used to quantify the chromium content in the passive coating as total chromium, metallic chromium, and chromium oxide. Morphological and chemical analyses using scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) were performed. The study was completed by conducting X-ray photoelectron spectroscopy (XPS) experiments in order to elucidate the passive layer chemical composition.

Titre : New anti-corrosive painting technologies at the beginning of the 21st century Type de document : texte imprimé Auteurs : E. Almeida, Auteur Année de publication : 2000 Article en page(s) : p. 73-84 Note générale : Bibliogr. Langues : Américain (ame) Tags : Matériau revêtement Peinture anticorrosion Protection corrosion Peinturage Acier galvanisé haute teneur solide poudre eau photodurcissable radiodurcissable Préparation surface Passivation Phosphatation Utilisation Article synthèse Index. décimale : 667.9 Revêtements et enduits Résumé : The aim of this work is to provide a general overview of current trends in anti-corrosive painting technologies for steel and galvanized steel substrates. After some considerations of important aspects inherent to the environment and humans and to competitiveness and quality, a of new painting technologies is given, in particular solvent-free liquid paints, powder paints, water-based paints, and radiation-cured paints. As a complement to this, mention is made of specific aspects concerning galvanized steel and application technologies, such as cataphoresis and autophoresis. Finally, some references are presented concerning the short- and mid-term future of anti- corrosive painting technologies.
