Abstract
Three types of polycrystalline diamond composites (PCDs) were studied. The first material was sintered using the mixture containing 80 wt.% diamond, 15 wt.% of Ti-Si-C powder (mixture of 47.1 wt.% Ti3SiC2 and TiSi2, TiC and SiC, from self-propagating high-temperature synthesis) and 5 wt.% nanometric Ti(CN) powders. The second material was prepared using diamond powder and 10 wt.% of titanium diboride. Materials were sintered using a Bridgman-type high-pressure apparatus at 8 GPa and at the temperature of 2000 °C. The third material was a commercial PCD containing 88 wt.% of diamond, 10 wt.% of Co and 2 wt.% of WC. The coefficients of friction for diamond composites in a sliding contact with an Al2O3 ceramic ball were determined from room temperature of up to 800 °C, in air. X-ray diffraction patterns of diamond composites after HP-HT sintering and wear tests are presented. In the studies, due to the use of Raman spectroscopy the strong influence of the bonding phase on the oxidation of diamond composites was confirmed. The most thermally stable material is the diamond composite with TiB2. High temperature bonding phase for diamond composites guarantees higher hardness and low coefficient of friction at elevated temperatures. © 2014 Elsevier Ltd.
