摘要

The microstructure and the mechanical properties of TiB₂ ceramics synthesized by the spark plasma sintering (SPS) process with Ti sinter-aid were investigated. The results indicate that the addition of 2.5 wt.% Ti significantly decreases the densification temperature of the TiB₂ ceramic. The TiB₂ ceramic sintered at 1650 °C exhibits the highest relative density of 99.1%, a microhardness of 26.8 ± 1.6 GPa, a flexural strength of 558 ± 39 MPa and a fracture toughness of 5.9 ± 0.3 MPa m^1/2.
