Title (EN) PRETREATMENT COMPOSITIONS, COATED ALUMINUM ALLOYS, AND METHODS OF MAKING THE SAME
(FR) COMPOSITIONS DE PRÉTRAITEMENT, ALLIAGES D'ALUMINIUM REVÊTUS ET PROCÉDÉS POUR LES PRODUIRE
Abstract:
(EN) Described herein are pretreatrnent compositions, coated aluminum alloy products, and methods for coating the alloys. The pretreatrnent compositions include inorganic chemical corrosion inhibitors dispersed in a silane-based matrix and may further include clay particles. The inorganic chemical corrosion inhibitors include rare earth metals and salts thereof. The pretreatrnent compositions, when applied to the surface of an alloy, inhibit corrosion of the alloys. The pretreatrnent compositions can be used in automotive, electronics, industrial, transportation, and other applications.
(FR) L'invention concerne des compositions de prétraitement, des produits en alliage d'aluminium revêtus et des procédés de revêtement des alliages. Les compositions de prétraitement comprennent des inhibiteurs de corrosion chimique inorganiques dispersés dans une matrice à base de silane et peuvent en outre comprendre des particules d'argile. Les inhibiteurs de corrosion chimique inorganiques comprennent des métaux des terres rares et des sels de ceux-ci. Les compositions de prétraitement, lorsqu'elles sont appliquées sur la surface d'un alliage, inhibent la corrosion des alliages. Les compositions de prétraitement peuvent être utilisées dans des applications automobiles, électroniques, industrielles, de transport et d'autres applications.
