Balbyshev, Auteur Année de publication : 2001 Article en page(s) : p. 35-43 Note générale : Bibliogr. Langues : Américain (ame) Tags : Protection corrosion Traitement surface Procédé sol gel Industrie aéronautique Application Nanostructure Réticulant Morphologie Alliage base aluminium Al93Cu4Mg2Mn1 Al Cu Mg Mn AA 2024 Index. décimale : 667.9 Revêtements et enduits Résumé : Current coatings for aircraft corrosion protection are based on chromate surface treatments, primers, and topcoats. One approach to developing a chromate-free surface treatment is through the use of sol-gel materials that interact strongly with both the substrate and the subsequent polymer layers. Results are reported here on a new sol-gel technique using a pre-formed, self-assembled, nano-phase particle (SNAP) sol-gel system. SNAP films have been investigated by infrared spectroscopy, atomic force microscopy, and electrochemical methods. Potentiodynamic polarization and electrochemical impedance spectroscopy demonstrated that the SNAP system generates high quality, defect-free, durable films. Formulation parameters, including crosslink density and coupling agent application, were optimized based on experimental results.

[article]
Titre : Optimization and performance analysis of copper immersion coating on AZ91 magnesium alloy Type de document : texte imprimé Auteurs : Lianxi Yang, Auteur ; Ben Luan, Auteur ; Woo-Jae Cheong, Auteur ; Jiaren Jiang, Auteur Année de publication : 2005 Article en page(s) : p. 493-498 Note générale : Bibliogr. Langues : Américain (ame) Tags : Métallisation Etude expérimentale Couche protectrice anticorrosion Matériau revêtement Plan expérience Condition mise en oeuvre Dépôt immersion Attaque chimique Traitement surface Magnésium alliage Cuivrage Optimisation Index. décimale : 667.9 Revêtements et enduits Résumé : An orthogonal experimental methodology was used to study a copper immersion coating on AZ91 magnesium alloy from a hydrofluoric acid-containing bath. Factors such as hydrofluoric acid concentration, sonication time, chemical etching, and activation process were considered in the design. The analysis of variance on the orthogonal experimental results was performed, resulting in an optimal condition for achieving a uniform copper coating with high coverage. Hydrofluoric acid was found to be an essential component in the copper immersion coating bath and a possible mechanism was suggested to explain its significance in terms of magnesium film destruction and magnesium dissolution.

[article]
Titre : Underfilm corrosion on polyurethane-coated aluminum alloy 2024-T3 containing dissimilar metal fasteners Type de document : texte imprimé Auteurs : A. E. Hughes, Auteur ; T. Markley, Auteur ; A. K. Neufeld, Auteur Année de publication : 2006 Article en page(s) : p. 313-322 Note générale : Bibliogr. Langues : Américain (ame) Tags : 'Vieillissement accéléré' 'Corrosion acide' Anticorrosion Nickel Cuivre Assemblage boulonné 'Assemblage mécanique' ' Aluminium Alliage Peinture 'Traitement de surface' Polyuréthane Index. décimale : 667.9 Revêtements et enduits Résumé : Panels of AA2024-T3 were fastened using Cu and Cu-Ni fasteners, pretreated, and coated with around 25 µm of polyurethane film. The pretreatments were based on typical conversion coating processes. Samples included alkaline-cleaned, deoxidized, and conversion-coated. The conversion coatings included chromate and cerium-based conversion coatings. Samples were tested by scribing around the fastener and on the AA2024-T3 (matrix), exposing them to HCl vapor for 15 min, and subjecting them to a filiform corrosion test by exposure to 82% relative humidity at 40 ± 1 °C for up to 1000 hr. Inspection showed that the filiform corrosion that developed from a scribe around the fastener was an order of magnitude larger than from a scribe on the matrix (scribe on AA2024-T3). With respect to the surface treatments, the amount of filiform corrosion for scribes on the matrix was greatest on the alkaline-cleaned samples, followed by the deoxidized samples, with the conversion-coated samples performing the best. The amount of filiform corrosion for scribes around the fasteners was highest for the deoxidized sample.
