Resum
Surface modification with cerium oxide of tetragonal zirconia polycrystals stabilised with 3 % molar yttria (3Y-TZP) has been investigated in order to avoid low temperature degradation. The surface modification was performed by annealing 3YTZP with surface coated CeO2 powder at temperatures of 1400 ºC and 1500 ºC for periods of time up to 10 hours. These heat-treatments diffused cerium up to about 10 mm depth. The bulk fracture toughness, Vickers hardness and Young modulus of the surface modif...
