Abstract
The effect of ultrasonic vibration grinding for mechanical properties of Al2O3/ZrO2 ceramics composite was studied in this work. The phase compositions and the microstructures of Al2O3/ZrO2 ceramics were investigated by XRD, SEM and TEM. Results indicated that the hardness and fracture toughness of Al2O3/ZrO2 ceramics could reach 1496Mpa and 9.44 MPa.m1/2 respectively, which increase 60% and 12% compared to that without ultrasonic vibration grinding.
