dc.descriptionIn 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 9.8X10(6) cm²s-1 while the AG for the formation of stable nucleus was 1.013X10(20) J/nuclei. The critical cluster's size calculated was 0 which suggested that each active site is a critical nucleus on the SSE-304 surface. The Scanning Electron Microscopy images showed the formation of non-uniform cobalt particles.
