Abstract

This contribution reports the fabrication of WC composites with 6 wt. % zirconia via spark plasma sintering (SPS) route. The sinterability, microstructure and mechanical properties of the SPS processed samples are compared with those fabricated by presseureless sintering. Fully dense WC composites with nano-ZrO2 reinforcement were obtained after SPS at a lower temperature of 1300°C (5 min). In contrast, high sintering temperature of 1600-1700°C is necessary to obtain fully dense WC composites via pressureless sintering. Superior hardness (21-24 GPa) is obtained with the newly developed WC- ZrO2 materials when compared to that of the WC-Co materials (15-17 GPa). Due to extremely high hardness, the WC-ZrO2 nanocomposites seem to be promising materials for wear applications.
