Title (EN) PREPARATION METHODS FOR ADHESIVE BONDING OF 7XXX ALUMINUM ALLOYS, AND PRODUCTS RELATING TO THE SAME
(FR) PROCÉDÉS DE PRÉPARATION PERMETTANT LA LIAISON ADHÉSIVE D'ALLIAGES EN ALUMINIUM 7XXX, ET PRODUITS ASSOCIÉS AUXDITS PROCÉDÉS
Abstract:
(EN) A preparation method for adhesive bonding of magnesium-containing aluminum alloy products includes a magnesium-containing aluminum alloy product including a matrix and a surface oxide layer overlying the matrix. The magnesium-containing aluminum alloy product also includes intermetallic particles at least proximal the surface oxide layer. The method also includes ablating at least some of the intermetallic particles via an energy source, and in the absence of melting of the matrix of the magnesium-containing aluminum alloy product.
(FR) L'invention concerne un procédé de préparation permettant la liaison adhésive de produits en alliage d'aluminium contenant du magnésium, qui comprend un produit en alliage d'aluminium contenant du magnésium comprenant une matrice et une couche d'oxyde de surface recouvrant la matrice. Le produit en alliage d'aluminium contenant du magnésium comprend également des particules intermétalliques au moins proximales à la couche d'oxyde de surface. Le procédé comprend également l'ablation d'au moins certaines des particules intermétalliques par l'intermédiaire d'une source d'énergie, et en l'absence de fusion de la matrice du produit en alliage d'aluminium contenant du magnésium.
