Abstract

L'invention porte sur un procédé d'électrodéposition d'or et d'alliages d'or à partir d'une solution exempte d'ions cadmium et cyanure libres comportant comme agent complexant de l'EDTA, du DPTA ou un chélateur similaire. La solution peut également contenir un matériau céramique se déposant avec les ions or afin de conférer aux produits finaux des propriétés mécaniques et physiques améliorées.
