Abstract

Procedimento per elettrodeporre nichelio su un substrato conduttore in modo da inibire l'accumulo di ioni nichelio nell'elettrolita. Un anodo di sacrificio e un anodo di ferro insolubile sono immersi in un bagno elettrolitico di nichelio.La corrente fornita all'anodo di ferro è controllata durante la placcatura per ridurre la quantità di nichelio che si accumula in soluzione.
