Rapid fabrication of the Ti3SiC2 bonded diamond composite by spark plasma sintering

A mixture of Ti/Si/TiC/diamond powders was employed to fabricate the Ti3SiC2 bonded diamond composite using the spark plasma sintering-reactive synthesis method. The addition of diamond does not inhibit the synthesis of Ti3SiC2 in the sintered product. In the matrix Ti3SiC2 grains developed lamellar morphology with an average length size of 5–10 μm. Ti3SiC2 matrix displays good pullout strength with diamond, and the Ti3SiC2 bonded diamond material exhibits good wear resistance.
