Rezumat:

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 cerium oxide (CeO2) particles has an influence on the codeposition process. The CeO2 included particles lead to structural modifications of the metal matrix and have an effect on the mechanical as well as the surface properties of the composite.
