Abstract:Anodic behavior of iron, cobalt, and nickel silicides with different silicon-to-metal ratios and that of pure silicon are studied in NaOH and NaOH + KCl electrolytes using cyclic voltammetry and x-ray photo-electron spectroscopy. Basic silicide dissolution regularities are revealed and compositions of the surface films are examined. Despite a high silicon solubility in alkaline electrolytes, due to protective properties of the surface oxide film of a complex composition, the silicides exhibit good anodic stability.
