Abstract
Tetragonal zirconia polycrystals doped with 3% mol of yttria (3Y-ZrO2) exhibit excellent mechanical properties and biocompatibility. However, under humid environments, their surface structural integrity is degraded by aging (low temperature degradation). Co-doping with Ceria by starting from mixtures of 3Y-ZrO2 and 12Ce-ZrO2 powders can increase the resistance to low temperature degradation. In this study, systematic chemical and nanomechanical measurements have been conducted in powder multilay...
