Dense AI203 particle-Y-TZP matrix (AI203 < 40 vol %) composite was prepared by pressureless sintering at 1550~ Composites with 10-30 vol % AI=O 3 particles showed enhanced fracture toughness, bending strength and Vicker's hardness as compared to singlephase Y-TZP. The highest strength (1150 MPa) and
Unlubricated friction and wear tests of CeβTZP/Al~2~O~3~ nanocomposites against bearing steel were performed. In order to elucidate the wear mecahnism, the morphological investigation and phase structural analysis of worn surfaces were carried out by Xβray diffractometer and scanning electron micros
