Electro-codeposition of CeO₂ nanoparticles into cobalt matrix to improve the tribocorrosion performances of Co/nano CeO₂ composite layers in biological solution for medical applications
Tijdschriftbijdrage - Tijdschriftartikel
Co/nano-CeO₂ composite layers were developed by electro-codeposition method from a cobalt electrolyte containing dispersed CeO₂ nanoparticles. The tribocorrosion performances of both Co/nano-CeO₂ and pure Co layers were comparatively investigated by sliding friction tests under lubricated condition in biological Hank solution. The effect of embedded nano-CeO₂ on the corrosion electrochemical response, friction coefficient and wear loss volume is analyzed. The results show that the codeposited of nano-CeO₂ particles into cobalt matrix reduce the friction coefficient and wear weight loss as well as the shift of open circuit potential to active state, increasing the polarization resistance and reducing the corrosion damages.
