- Opis:
- This research paper aims to study the influence of some of the main parameters applied to the electrodeposition process on the nanocomposite layers obtained by strengthening the cobalt matrix with cerium oxide nanoparticles. Thus, the current efficiency (process efficiency) and the degree of inclusion of cerium oxide nanoparticles into cobalt matrix are analyzed according to the current density, the concentration of nanoparticles dispersed in the deposition electrolyte and time of the process. The choice of the optimal parameters imposed on the electrodeposition process lead to the improvement of the quality of the obtained layers, to the reduction of production costs and last but not least to the improvement of corrosion and tribocorrosion resistance of the material. The obtained results show an increase of current efficiency in the process of the deposited layers with the increase of time and current density applied. There is also a slight increasing in the current efficiency of the obtained layers with the increase of the concentration of nanoparticles dispersed in the deposition electrolyte. The increase of the current density, time and the concentration of nanoparticles also have an effect on the degree of embedded CeO2 nanoparticles into cobalt matrix for the studied nanocomposite layers. The degree of inclusion of nanoparticles decreases for the same studied system with the increasing of the current density.
