Effects of alloying elements addition on the as- cast Co-Cr biomedical alloys

Effect of alloying elements Mo, Ni and Ti on the microstructure and properties of Co-Cr alloys has been studied on 12 experimental samples. The microstructural examinations show that the most of as-cast alloys have similar two-phases eutectic dendritic microstructure. Hardness of alloys increases with titanium, molybdenum and chromium content and decreases with nickel content. According to the Epit- values Co-Cr-Ti alloys reveal prominent corrosion characteristics.
