Abstract

L'invention concerne l'électrodéposition d'un alliage or-cobalt. Elle se rapporte à un procédé dans lequel un courant électrique circule entre une anode et un substrat placé dans un bain qui contient du cyanure de potassium et d'or, de l'acide nitrilotriacétique et un sel de cobalt; ce dernier donnant dans la solution une quantité de cobalt de 0,1 à 7,0 g/l, le pH du bain utilisé étant compris entre 3,5 et 6,0. Le sel de cobalt est avantageusement un sulfate et la densité de courant est avantageusement comprise entre 0,1 et 11 A/dm**2. Application au dépôt d'alliage or-cobalt sur des contacts électriques.
