Abstract

Procedimiento perfeccionado de electrolisis, de aplicación en un baño de galvanoplastia cuyo electrolito contiene de 13,5 a 40,4 gr/l de cianuro de zinc, de 10,6 a 31,7 gr/l de cianuro de cobre, de 30,0 a 52,5 gr/l de cianuro de sodio (libre) y de 15,0 a 45,0 gr/l de hidróxido de sodio, caracterizado porque se ajusta el ph entre valores 10-13, posteriormente se incorpora una composición aditiva que actúa como agente amortiguador y que esta seleccionado de entre el grupo formado por el ácido bórico, los boratos metálicos alcalinos, los fosfatos metálicos alcalinos, los carbonatos metálicos alcalinos y la glicina, mezclado con un ion metálico que se elige del grupo formado por el ion de níquel y el ion de cobalto y con un ácido acético etileno-diamino-tetra tal como la sal metálica alcalina.
