The codeposition of Al2O3 and TiO2 from the acid copper electrolyte was investigated with respect to solution pH, particle concentration in the electrolyte, addition agents and the nature of the crystalline phase of the oxide particles. The incorporation of oxides was found possible without the need of addition agents, provided the oxide particles are of the favorable crystalline form as α-Al2O3 and rutile TiO2. A technique is reported whereby the γ-Al2O3 particles are partially transformed to the α-form making the oxide suitable for codeposition.
