Sažetak
There are a number of advantages of using titanium alloys for biomedical applications. The purpose of this investigation was to examine the effects of alloying and heat treatment on the microstructure and hardness of biomedical Ti-Cr-Co alloys. This paper shows that the microstructure and hardness are dependent on the addition of alloying elements as well as heat treatment of Ti-Cr-Co alloys. Samples were prepared by melting pure elements in a laboratory arc furnace under an argon atmosphere. They were metallographically prepared and analyzed with the X-ray diffraction method. Microstructures of experimental alloys were taken with digital camera and analyzed with computer program Image Tool. Hardness was measured using the Vickers indentation method. Heat treatment was carried out at 950°C over 3 hours with quenching in water. The microstructure and hardness were analyzed after the heat treatment. The results obtained show heat treatment effects the volume ratio of phases in alloys with 10 at.% of cobalt, but alloys with 5 at.% of this alloying element were retained as single-phase. Also, hardness of investigated alloys depends on content of alloying elements (chromium and cobalt), but the effect of heat treatment on the hardness of this alloys was negligible.
