Abstract

In this study, the electrochemical behavior and tribocorrosion performance of cobalt-chromium (Co-Cr) alloys produced by different fabrication methods (casting and CAD/CAM milling technique) have been investigated in the laboratory-simulated artificial saliva. The results have shown that the maximum tribocorrosion resistance was obtained for milled Co-Cr alloy because of higher corrosion resistance and hardness of milled Co-Cr alloy compared too those of cast Co-Cr alloy. Moreover, the lowest friction coefficient was achieved for milled Co-Cr alloy.
