Abstract
Phase transformation of 3Y-TZP with different ternary oxide additions (Al2O3, La2O3, Sc2O3 and CeO2) was evaluated by hydrothermal degradation tests in water vapor at 180°C. Monoclinic phase quantification from XRD patterns showed an improved degradation resistance of the specimens with oxide additions in comparison to the 3Y-TZP base material. Cross sectional sample analysis showed that, even though for all the compositions the exposed surface became saturated with monoclinic phase, the penetration of the transformation varied. Alumina-lanthana doped materials exhibited the thinnest degraded layer.
