Notes:
Nanocomposite WC-10Co powder produced by spray pyrolysis-continuous reduction &carbonization technology and cubic boron nitride (CBN) plated with titanium by vacuum vapor depositwere used, and this paper adopted spark plasma sintering (SPS) process to prepare CBN enhancedultrafine WC-10Co cemented carbide cermets composite material. The microstructure and mechanicalproperties of CBN-WC-10Co composites were investigated. The results show that CBN-WC-10Cocomposites consolidated by spark plasma sintering can reach 95.0 % relative density, and transverserupture strength (TRS) is 1050 MPa, the average grain size of cermets matrix is less than 420 nm, andCBN-WC-10Co composites with excellent properties are achieved. The CBN still remains very goodcrystal shape after 1240°C spark plasma sintering, and there is not obvious clearance between CBN platedwith titanium and the cermets matrix, the coated titanium layer can not only improve the thermal stabilityof CBN, but also increase the properties of CBN-WC-10Co composites
