Mechanism of cobalt deposition was investigated using the potentiodynamic potentiostatic methods in solution of pH 4 and pH6.4 In all experimental conditions, polarization curves showed two regions with different Tafel slopes and the reaction order of cobalt ion was varied with the pH. It is belived that the deposition mechanism depends not only on the portential but also on the ph.
