Yabuki, Auteur ; W. Urushihara, Auteur ; J. Kinugasa, Auteur Année de publication : 2012 Article en page(s) : pp. 907–912 Note générale : Génie Mécanique Langues : Anglais (eng) Mots-clés : Aluminum Composite coating Particle Polymer Self-healing Résumé : TiO2 particle–polymer composite coatings were applied to the surface of a 5083 aluminum alloy. After using a knife to create an artificial defect, polarization resistance was monitored in artificial seawater at a temperature of 30 °C. The polarization resistance of the specimen coated with the composite polymer containing 3 vol% TiO2 particles increased significantly over time, suggesting that the composite coating had self-healing properties. A carbon-containing 2-µm thick film was found on the coated aluminum substrate at the site of the artificial defect. The formation of the film was related to the dissolution of bisphenol A (BPA), which is a chemical precursor of the polymer coating that behaved as an inhibiting agent.
