    • Abstract

  • SiC whiskers (SiCw)/WC binderless cemented carbides were prepared by spark plasma sintering (SPS), using SiCw as the toughening phase. The effects of sintering temperature and SiCw content on the microstructure and properties of the SiCw/WC cemented carbides were investigated. The results show that the WC sintered body with the relative density higher than 99% can be obtained by spark plasma sintering at 1800 ℃, and the Vickers hardness and fracture toughness reach 25.99 GPa and 4.99 MPa∙m1/2, respectively. The sintering properties and fracture toughness of the SiCw/WC sintered body can be improved by adding the appropriate amount of SiCw. The fracture toughness reaches 6.80 MPa∙m1/2 with the SiCw mass fraction of 0.6%. However, the toughening effect to the WC matrix decreases with the further increase of content SiCw.
