In this paper, the field activated and pressure assisted synthesis (FAPAS) were used for preparing the ultra-hard, super-abrasive AlMgB14∕TiB2 composite ceramic. We analyzed how the ultra-fine TiB2 particles influence microstructure and toughness of samples by using scanning electron microscopy (SEM), energy dispersive analysis (EDS) and X-ray diffraction (XRD) respectively. The wear resistence and tribological behavior of AlMgB14∕TiB2 composite materials at 25℃, 300℃,500℃ were characterized throughing high-temperature friction and wear test. The results show that the average hardness of AlMgB14∕TiB2 composite materials reached 32.5 GPa after adding 30 wt% submicron scale TiB2 particles. The fracture toughness was seen to increase from 3.0 to 3.95MPa? m1/2. Friction coefficient ranged from 0.4 to 0.5 at room temperature and 300℃ , this figure exhibited approximately 0.65 in the case of 500℃ sliding operation. The specific wear rate ranged from 1.27?0-6 mm-3/（N?m）to 6.62 mm-3/（N﹒m）.With increasing the test temperature, The tribological properties of AlMgB14∕TiB2 composite materials changed, As a result of the friction surface oxide lubrication, friction coefficient decreased at 300℃，the wear mechanism from abrasive wear at room temperature to adhesive wear .
