TiB2/WC/h-BN micro-nano composite gradient self-lubricating ceramic tool material was prepared by vacuum hot-pressing technique. The mechanical properties were tested and compared. The best flexural strength, fracture toughness and Vickers hardness of the tool material were 678MPa, 4.75MPa·m1/2 and 15.1GPa, respectively. The microstructure was analyzed by thermal field emission scanning electron microscope (SEM). TiB2 nanoparticles were obviously observed in the ceramic matrix. It suggested that the developed TiB2/WC/h-BN micro-nano composite gradient self-lubricating ceramic tool materials will have potential application in dry machining.
