Abstract

L'invention vise à mettre en oeuvre un procédé de galvanisation permettant de revêtir galvaniquement et de passiver simultanément des objets conducteurs, de façon simple et économique. A cet effet, un substrat est immergé dans un bain de galvanisation contenant des ions d'au moins un métal pour le dépôt électrochimique sur la surface du substrat, des ions d'au moins un métal de transition et un solvant, le substrat formant la cathode d'une cellule électrochimique; une tension est appliquée à la cellule électrochimique de manière à produire un flux de courant qui entraîne le dépôt au moins du ou des métaux sur la surface du substrat; après dépôt du ou des métaux, le flux de courant est interrompu; puis un potentiel est produit sur la cathode ou une électrode supplémentaire réalisée dans le matériau du substrat, pouvant être connectée de façon conductrice au substrat, est immergée dans le bain de galvanisation et conservée ou maintenue immergée pendant un intervalle de temps.
