Electrochemical behavior of this binary alloy was studied by cyclic voltammetry (CV) with a paraffin impregnated graphite electrode (PIGE) as a working electrode. Deposition of individual metals (Ni, Co), as well as the simultaneous nickel-cobalt co-deposition, was performed in aqueous solutions (Watts-type electrolyte) both with and without Fe powder. Special attention was paid to the influence of suspension density on the electrode process. This density affects on the quality of iron powder electroplating. Preferential deposition of the less noble metal (Co) leading to its higher content in the deposit was observed in contrast to the more noble one (Ni) in spite of higher content of Ni in the plating solution. Understanding the anomalous behavior would lead to better control of the deposition process and to explanation of the mechanism of Ni-Co co-deposition. ER -
