Composite layers were obtained by electrochemical deposition of cobalt or nickel from a plating bath with cerium oxide as dispersed particles. The changes in microstructure and microhardness of the composite were studied in correlation with the number of oxide particles incorporated. It was found that the presence of zirconium oxide (CeO2) particles has an influence on the codeposition process. The CeO2 included particles lead to structural modifications

Electrocodeposition is a method successfully used to obtain composite coatings. The composite coatings in nickel matrix and nano-Al2O3 particles (20 nm) as dispersed phase were obtained from a Watts electrolytic bath at a current density of 3A/dm2. The concentration of nano-Al2O3 was 5, 10 and respectively 20g/L oxide in the bath. The effect of the embedded of Al2O3 nanoparticles in nickel matrix was studied. The surface morphology of layers was

Silica-based nanocomposite thin films with mesoporous structure are very interesting materials for gas sensing applications. The porosity of matrix provides a path for the gas molecules to reach the functional oxide nanoparticles and the films show reversible change in resistance and/or optical transmittance in the VIS-NIR range when exposed to gases. Co oxides-SiO2 and ZnO-SiO2 mesoporous nanocomposite thin films have been obtained using a pre-hydrolyzed

Cu-nanoTiO2 composite coatings electroplated from copper sulphate bath were obtained and characterised. The paper presents the influence of the concentration of TiO2 nanoparticles as dispersed phase in copper matrix coatings obtained at different current densities. The concentrations of nano-TiO2 particles (17nm) were 5, 10 and respectively 50g/L in electroplating bath. It was shown that the mechanism of electrodeposition affected the incorporation
