Abstract

Un procedimiento para realizar la galvanoplastia de aluminio, que comprende poner en contacto dicho aluminio con un baño activador acuoso sustancialmente exento de iones cobre activos que contiene una sal de estannato seleccionada del grupo constituido por estannato de sodio y estannato de potasio en una concentración de 10 a 70 gramos por litro de estaño como estannato; al menos un miembro del grupo constituido por hidróxido de sodio y de potasio en una concentración comprendida entre 1,2 gramos por litro y 12,0 gramos por litro; y 0,01 gramos por litro a 25 gramos por litro de al menos un miembro del grupo constituido por éteres de metilcelulosa, poli (alcoholes vinílicos), poli (óxido de etileno), y polietilenglicoles; mantener dicho aluminio y dicho baño acuoso en contacto para evitar así la superficie de dicho aluminio, retirar de dicho baño acuoso dicho aluminio que lleva una película de dicho baño acuoso, sumergir dicho aluminio que lleva dicha película como cátodo en un baño alcalino de bronce que contiene un ánodo para depositar de este modo una placa de adherencia sobre dicho aluminio, y establecer un potencial negativo sobre dicho aluminio que lleva dicha película con respecto a dicho ánodo antes del momento en que dicho aluminio se sumerge en dicho baño alcalino de bronce.
