Abstract

In this paper, ultrasonic surface finishing has been introduced to the electro-discharge machined (EDMed) Al2O3/TiC/Mo/Ni ceramic composite. Thermal shock behavior of the EDMed and the modified ceramic specimens was investigated by water quench tests. Statistical analysis was used to evaluate the thermal shock behavior by measuring the retained strength and determining the strength distributions. Results show that under no thermal shocking conditions, ultrasonic surface finishing for the EDMed ceramic specimens can yield an apparent strengthening with a concurrent increase in Weibull modulus. During rapid quenching, the retained strength and the Weibull modulus of the EDMed specimens can be greatly improved by ultrasonic surface finishing until the temperature difference reaches its critical value (DeltaT(c)).
