Abstract In the present paper, data on the codeposition of fine Al2O3 particles with copper from an acidified copper sulphate bath and on the codeposition of Au-Al2O3 from a gold cyanide bath are compared. Based on these results, it is shown that the mechanism of codeposition of inert particles is similar in both systems. The reduction of ions adsorbed on alumina particles is the rate-determining step. The rate of codeposition is further dependent on the mass transport to the electrode and on the applied voltage. Based on the information gained from these experiments on the electrolytic codeposition of inert particles with a metal, the electrolytic deposition process of the pure metal and the incorporation of foreign ionic species in such an electrolytic deposit are discussed.
