dc.description.abstractThis research work focuses on the mechanical properties and microstructural behavior of high-purity CeO2 and MnO2-doped Y-TZP. The compositions were varied with different weight percentage i.e from 0.5 to 1.5wt%. The samples were homogenously mixed using wet milling and ball milling operations. Then, the samples were shaped into circular discs and rectangular bars by uniaxial pressing at 200 MPa and then pressure less-sintered at various temperatures between 1250?C and 1450?C. 1h holding time was applied before cooling down. The results have shown, that the addition of dopant and sintering temperature has significantly contributed towards the enhancement of the mechanical properties of Y-TZP. The mechanical properties in relation to bulk density, Young�s modulus, Vickers hardness, and flexural were measured. The best mechanical property values for the CeO2 and MnO2-doped Y-TZP ceramics were 5.67 Mgm-3 and 8.46 GPa for density and Vickers hardness, respectively. The best flexural strength and Youngs modulus values obtained from the experiment were ~900 MPa and 210 GPa respectively. These results indicate that the addition of dopants have reinforced the densification parameters and toughened the samples. These results were obtained for the composition of 0.5wt% MnO2 and 0.5wt% CeO2 sintered at 1350?C. � BEIESP.en_US
