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 H₂.
