The electrolytic codeposition of nanometric size TiO2 particles with copper from an aqueous electrolyte has been investigated. Two crystalline modifications of TiO2 - anatase and rutile were used to prepare a nanodispersed suspension. Qualitative dispersion- hardened Cu-TiO2 composite coatings were obtained with the reproducible results only from a freshly prepared concentrated electrolyte-suspension. It has been revealed that nanodispersed materials can be obtained electrochemically with an anatase sort of titania. Rutile powder is not as suitable as anatase for this purpose.
