Abstract
The effect of CeO2 addition in zirconia toughened alumina (ZTA) was examined. The CeO2 addition in weight percent (wt %) was varied from 0 wt% to 15 wt%. The fabricated samples were sintered at a temperature of 1600°C. The sintered samples were characterized their properties such as fracture toughness and phase determination. X-ray diffraction patterns confirm the constituent phases present in the samples were alumina and zirconia. Fracture toughness for each sample in the range of 5.878.38 MPam1/2 respectively. It was observed that the addition of ceria increased the fracture toughness of the zirconia toughened alumina ceramic composites.
