Abstract
In this study, we investigated the propagation of ultrasonic waves in ceramic composite. Providing some samples of Al2O3 ceramics, ZrO2 ceramics and Al2O3/ZrO2 composite with different Al2O3 content, the effects of both pores and Al2O3 particles on the ultrasonic velocity (P wave speed) were examined. Resulting from the ultrasonic tests, the following facts were revealed : (1) In the porosity range below 20%, the ultrasonic propagation time increases in proportional to the porosity. (2) The ultrasonic propagation time decreases linearly with the increase in volume fraction of Al2O3 (3) The ultrasonic velocity is independent of the particle size of Al2O3 powder. We derived the relationship equations among ultrasonic velocity. Al2O3 content and porosity.
