Reliability assessment in advanced nanocomposite materials for orthopaedic applications
Jérôme Chevalier, Paola Taddei, Laurent Gremillard +8
Alumina-zirconia nano-composites were recently developed as alternative bearing materials for orthopedics. Previous, preliminary reports show that such alumina-zirconia nanocomposi…
Atomic force microscopy study of the surface degradation mechanisms of zirconia based ceramics
Sylvain Deville, Jérôme Chevalier, Gilbert Fantozzi +3
Atomic force microscopy (AFM) can be used to characterise several aspects of the surface degradation and reinforcement mechanisms of zirconia based ceramics, such as crack propagat…
Accelerated Aging in 3 mol%-Yttria-Stabilized Tetragonal Zirconia Ceramics Sintered in Reducing Conditions
José Bartolomé, Isabel Montero, Marcos Diaz +6
The aging behavior of 3-mol%-yttria-stabilized tetragonal zirconia (3Y-TZP) ceramics sintered in air and in reducing conditions was investigated at 140°C in water vapor. It was obs…
Low-temperature ageing of zirconia-toughened alumina ceramics and its implication in biomedical implants
Sylvain Deville, Jérôme Chevalier, Gilbert Fantozzi +5
Changes in crystalline phases resulting from low-temperature ageing of different yttria doped and non-doped zirconia-toughened alumina composites and nanocomposites were investigat…
Microstructural investigation of the aging behavior of composites
Sylvain Deville, Jérôme Chevalier, Christelle Dauvergne +4
The low temperature autoclave aging behavior of zirconia toughened alumina composites processed by a classical powder mixing processing route was analyzed using atomic force micros…
Modeling the aging kinetics of zirconia ceramics
Laurent Gremillard, Jérôme Chevalier, Sylvain Deville +2
Yttria-stabilized tetragonal zirconia polycrystals (3Y-TZP) with different microstructures were elaborated. The isothermal tetragonal to monoclinic transformation was investigated…
A critical comparison of methods for the determination of the ageing sensitivity in biomedical grade yttria stabilized zirconia
Sylvain Deville, Laurent Gremillard, Jérôme Chevalier +1
Since the recent failure events of two particular series of zirconia femoral heads for total hip replacement prosthesis, a large decrease in the use of zirconia ceramics for orthop…
How do the grains slide in fine-grained zirconia polycrystals at high temperature?
M. Daraktchiev, R. Schaller, L. Gremillard +3
Degradation of mechanical properties of zirconia polycrystals is hardly discussed in terms of solution-precipitation grain-boundary sliding due to experimental controversies over i…
