Electrodeposition of copper in the presence of cadmium

Abstract

A study was made of the effect of cadmium concentration on the process of copper electrocrystallization from an ethylenediamine electrolyte on the (111) crystallographic plane of a copper single crystal. It was shown that a relation exists between superpolarization and depolarization of deposition of Cu-Cd alloy components, and cadmium underpotential adsorption or underpotential deposition. This relation was also detected by the influence exerted on the kinetic parameters of the given model of Cu-Cd alloy nucleation and growth. © 1979.
