"Kinetics of cobalt cementation on zinc sheet from solutions of cobalt sulphate have been investigated with respect to temperature, stirring velocity, and acidity. The effect of buffered solutions on the reaction rate has also been determined. The rate of the cementation reaction was found to be strongly influenced by the presence of metallic ions other than cobalt in the solution. This effect is interpreted in terms of "alloy" formation, whereas the difficulties encountered in cementing cobalt in the absence of metallic ions is explained in terms of cobalt deposition overvoltage, hydrogen overvoltage, and inhibition by co-deposition of zinc"--Abstract, page i.
