AB - This investigation focused to develop 5 wt.% cerium oxide (CeO2) reinforced inside Zirconia Toughened Alumina (ZTA)ceramics for evaluation of functional properties which is still unexplored. At first, the homogeneous composites of CeO2/ZTAand ZTA are developed through powder metallurgy process sintered at 1600 oC. The morphological characterization ofdeveloped composites are carried out through field emission scanning electron microscopy (FESEM) and x-ray diffraction(XRD) followed by mechanical characterization on Vickers hardness tester. The morphological study reveals that theincorporation of CeO2 grains increases the average grain sizes of composites, adversely affect on the bulk density. The retentionof high amount of metastable tetragonal phases due to presence of CeO2 grains evaluated through XRD phase analysis showsbeneficial effect on hardness and fracture toughness. Furthermore, the significant improvement of 15.07% in fracturetoughness is attributed to the transformation toughening, crack bridging and deflection phenomenon. Formation of glazy andsmooth surface is responsible for improvement in coefficient of friction (COF) by 24.45% compared to parent matrix. Highabrasion, micro cracks, grain pullout are predominant factors responsible for wear on the ZTA surface, whereas, grain pulloutand micro cracks formation are responsible for wear in CeO2/ZTA.
