Abstract

The nanocomposite CeO2/Y2O3 partially stabilized zirconia (Ce-PSZ/Y-PSZ)-toughened alumina was prepared by wet chemical simultaneous coprecipitation process. The thermal stability of phases and morphology of powders were characterized by TG-DTA, FTIR, and FESEM. The microstructure, stabilization of phases and compositional analysis with different mol% CeO2/Y2O3-doped zirconia in alumina are characterized by FESEM, XRD, and EDAX spectra. Significant improvement in fracture toughness and flexural strength has been observed in 10 vol% of partially stabilized zirconia (2.5 mol% Y2O3 in ZrO2/ 9 mol% CeO2 in ZrO2)-toughened alumina, which is suitable for high-speed machining applications.
