| Abstract: | The effects of Y_2O_3,CeO_2,La_2O_3 and complex rare earth oxides on the mechanical properties and the microstructure of zirconia toughened alumina(ZTA) ceramics be prepared via hot-pressed sintering were studied.The experimental results show that the microstructure and the sinterability of ZTA can be improved by proper rare earth oxides,High density and mechanical properties are also obtained.It is also found that different rare earth oxides and amount have different influence on the microstructure and the mechanical properties of ZTA. |
