Abstrak

In order to improve the mechanical properties of B4C ceramics, B4C@TiB2 composite powders with core-shell structure are prepared by molten salt method using B4C and Ti powders as raw materials. And B4C ceramics were prepared from B4C@TiB2 composite powders by spark plasma sintering (SPS). The results show that the B4C@TiB2 composite powders exhibit intact core-shell structure. The B4C@TiB2 composite powders improves the mass transfer during spark plasma sintering. When the molar ratio of B4C/Ti is 2/1, the relative density, Vickers hardness, fracture toughness and flexural strength of the BT1/2 sample are 94.2%, 26.9 GPa, 5.34 MPa·m1/2 and 570 MPa, respectively, which is best comprehensive properties.
