摘要：

This study investigated the effect of copper oxide addition on the alumina toughened zirconia composite ceramic using microwave sintering. CuO amounts (0.05-1 wt%) were examined at sintering temperatures (1250-1500 degrees C). Investigations covered hardness, toughness, phase stability, microstructure, and densification. Optimum doping was 0.2 wt %, resulting in a composite with 99% relative density at 1500 degrees C, Vickers hardness of 13.1 GPa, and fracture toughness of 7.1 MPa m1/2. Low-temperature degradation showed disrupted phase stability above 1400 degrees C, with CuO unable to prevent ageing-induced phase transformation. (c) 2023 The Author(s). Published by Elsevier B.V.
