Effect of Ultrasonic Vibration Grinding for Mechanical Properties of Al₂O₃/ZrO₂ Ceramics

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.m^1/2 respectively, which increase 60% and 12% compared to that without ultrasonic vibration grinding.
