Popis: |
Simultaneous additions of SrO and Al2O3 to ZrO2 (12 mol.% CeO2) lead to the in-situ formation of SrO·6Al2O3 platelets in the Al2O3/Ce-tzp matrix. These composites have superior damage resistance compared to Al2O3/Y-tzp ceramics despite their lower strength. The increased damage resistance appears to be primarily related to the higher residual stress as a result of grinding with smaller contributions due to micromechanical toughening. High damage resistance was also obtained by introduction of temperature-induced surface compressive stresses in layered composites. Damage resistance is only obtained at low temperatures ( |
