Abstract

Bains électrolytiques pour le dépôt d'alliages d'or. Ces bains basiques au sulfite, exempts de cyanure, comprennent de l'or, sous forme de complexe d'aurosulfite, un sulfite soluble dans l'eau, un agent de transformation en complexe ou de chélation et, également, un sel ou un complexe ou un chélate (soluble dans l'eau) d'un second métal d'alliage; l'agent de transformation en complexe contient au moins un acide contenant de l'azote et/ou du phosphore dont le pK pour le zinc est compris entre 6 et 15, et au moins un hydroxyacide choisi parmi des hydroxyacides acycliques ayant au moins deux groupes OH et des hydroxyacides cycliques aliphatiques ou aromatiques, le métal d'alliage étant choisi parmi l'indium et le gallium. La présente invention est particulièrement utile pour le dépôt électrolytique d'alliages or-zinc, à faible nombre de carats, blanc-gris, homogènes et brillants.
