Abstract

L'invention concerne des revêtements anti-corrosions pour des alliages de magnésium, utilisés dans l'industrie automobile et aéronautique, et leur procédé de préparation. En particulier, elle concerne les compositions de revêtement, les films formés sur le substrat et les propriétés anti-corrosion du système global lorsqu'il est immergé dans un électrolyte agressif. De façon plus spécifique, les revêtements consistent en un constituant époxy (par exemple poly(bisphénol A-co-épichlorohydrine), à extrémité coiffée par glycidyle), un silane (par exemple l'AminoPropylTriEthoxysilane, APTES) et une amine (par exemple la Diéthylènetriamine, DETA), dans des solvants organiques. La solution de revêtement peut être appliquée sur des substrats d'alliages de magnésium par revêtement par immersion ou pulvérisation, suivi par un durcissement thermique dans une plage spécifique de conditions. L'épaisseur du revêtement varie de 5 à 20 micromètres. Les alliages de magnésium revêtus par de tels films possèdent une excellente résistance à la corrosion et après une immersion d'un mois dans du chlorure de sodium, leur performance est remarquablement plus élevée par comparaison à des revêtements classiques, tels que présentés dans l'état de la technique.
