COBALT ELECTRODEPOSITION ONTO STAINLESS STEEL 304 FROM AMMONIACAL SOLUTIONS

In this work we studied the cobalt electrodeposition onto a stainless steel 304 electrode from an aqueous solution containing 10¹ M of CoSO4 + 1M (NH4)2SO4 at natural pH of 4.5. Black cobalt deposits were obtained under our experimental conditions. The average diffusion coefficient calculated was 9....
