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…
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…
Influence of surface finish and residual stresses on the ageing sensitivity of biomedical grade zirconia
Sylvain Deville, Jérôme Chevalier, Laurent Gremillard
We demonstrate in this paper the influence of surface finish on the ageing kinetics of biomedical grade zirconia. The critical influence of polishing has been systematically invest…
Atomic force microscopy study of the tetragonal to monoclinic transformation behaviour of silica doped yttria-stabilized zirconia
Sylvain Deville, Jérôme Chevalier, Laurent Gremillard
The tetragonal to monoclinic phase transformation of zirconia has been the subject of extensive studies over the last 20 years [1-4]. The main features of the transformation have b…
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…
Degradation of alumina and zirconia toughened alumina (ZTA) hip prostheses tested under microseparation conditions in a shock device
Juliana Uribe, Jean Geringer, Laurent Gremillard +1
This paper considers the degradation of alumina and zirconia toughened alumina vs. alumina for hip implants. The materials are as assumed to be load bearing surfaces subjected to s…
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…
