MATEIS laboratory and RMS Foundation are offering a one-year post-doctoral fellowship, with the aim of investigating the effect of surface distortions on mechanical properties and LTD resistance of the materials, as a function of different types and degrees of mechanical surface modifications.

The CNRS, INSA Lyon, Claude Bernard Lyon 1 University (UCBL) in Lyon (France) and RMS Foundation in Bettlach (Switzerland) recently collaborated on a project that aimed at characterizing in depth the lattice distortions and residual stresses in Yttria-Stabilized Zirconia Ceramics (Y-TZP) for biomedical applications generated by mechanical modification of their surface (treatments like polishing, grinding and sandblasting). The main objective of the project is understanding the cause and effects of the distortions and relate them to mechanical performances and long term reliability of these ceramics, and it is, therefore, an indispensable contribution to further improve the stability and longevity of Y-TZP implants.

During the first year of the collaboration, a crystallographic model for surface distortions in Yttria-Stabilized Zirconia Ceramics (Y-TZP), based on XRD Rietveld refinement and developed by N. Döbelin, was confirmed with complementary advanced microstructural characterizations. The following step will be to characterize the influence of such distortions on mechanical properties and Low Temperature Degradation (LTD).
