It was observed that the inclusion of Al 2 O 3 and MnO 2 into 3Y-TZP was beneficial for the improvement of mechanical properties and ageing resistance. The optimum amounts of dopants were determined to be of 0.6 wt% Al 2 O 3 and 0.4 wt% MnO 2 . Microstructural investigation revealed that at the same temperature, the tetragonal grain size was not influenced by the increase of dopant levels. With optimum dopants the 3Y-TZP ceramic (density 6.1 g/cm 3 ) samples demonstrated the Vickers hardness of 11.6 GPa, fracture toughness, K IC of 9.8 MPa m 1/2 , flexural strength of 900 MPa and Young's modulus of 210 GPa. Furthermore, the efficacy of the dopants (MnO 2 and Al 2 O 3 ) in retarding low-temperature degradation of 3Y-TZP ceramic during exposure in Ringer's solution at 37 �C was also evaluated. Overall, the degradation rate and weight loss of 0.6 wt% Al 2 O 3 and 0.4 wt% MnO 2 ceramic samples were 0.66% in 8 weeks as compared to the undoped samples. The 3Y-TZP bioceramic doped with Al 2 O 3 and MnO 2 could be a potential candidate material for biomedical applications (e.g. hip implants) due to its improved mechanical properties and superior ageing resistance. � 2018 Brazilian Metallurgical, Materials and Mining Association.
