Abstract:
Titanium (Ti)-nanodiamond (ND) composite discs were sintered using spark plasma sintering (SPS). Several parameters were studied such as the mixing technique, the heating rate and the applied pressure. The effect of these parameters on the densification of Ti + ND composites was shown. The mixing techniques and the applied pressure have a great influence on the densification of Ti + ND composites. The heating rate also has an influence, but less so for the mixing technique and applied pressure parameters. This study determines the optimized sintering parameters for the Ti + ND composites. Density, hardness and electrical conductivity were measured. The higher the ND content in the Ti + ND powder, the more the TiC solid phase forms in the composite which increases the hardness and reduces the electrical conductivity. At a given temperature, the density decreases with increasing ND content.
