Abstract

For co_deposition of Zn_Co alloys at sufphate baths with micro_concentration of SCN- the transition current of Zn was found with the deposition process changing from normal Co_deposition to anomalous co_deposition, and the value of transition current increased with increasing SCN- concentration, but decreased with increasing value of pH. The existence of SCN- decreases the evolution overpotential of Co metal, but has no effects on the evolution overpotential of Zn metal and H2.
