Abstract

L'invention a pour objet un bain d'électrodéposition d'un alliage d'or. Il contient un cyanure d'or soluble, du cadmium sous forme d'un composé, complexe ou chélate soluble dans le bain et une amine ou imine permettant d'introduire une petite quantité de carbone dans l'alliage afin de réduire d'au moins 15 % le rendement cathodique du bain. L'amine peut être une alkylpolyamine et l'imine peut être une polyalkylène-imine. Ce procédé trouve un intérêt particulier pour la fabrication de connecteurs et contacts électriques.
