Abstract

Anodic dissolution of cobalt suicides Co2Si, CiSi, CoSi 2, CoSi2-Si (eutectic alloy), and also individual Co and Si in 0.1-5.0 N NaOH solutions is studied by using cyclic voltammetry (CVA). In alkaline electrolyte, despite the increasing activity of silicon, the electrode is passivated due to the formation of protective films of cobalt oxides and hydroxides. The anodic stability of cobalt increases with a decrease in metal content.
