Influence of dopants on thermal stability and densification of β-tricalcium phosphate powders

Nicolas Somers, Florian Jean, Marie Lasgorceix, Hugo Curto, Giovanni Urruth, Anthony Thuault, Fabrice Petit, Anne Leriche

In this work, β-tricalcium phosphate (β-TCP) is doped with Mg2+ and Sr2+ in order to postpone the problematic β-TCP → α-TCP transition occurring from 1125 °C. Indeed, this phase transition occurs with a large lattice expansion during sintering causing microcracks and a reduced shrinkage leading to…

The complete discretization of the dual mixed method for the heat diffusion equation in a polygonal domain

Luc Paquet, Réda Korikache

The purpose of this paper is to prove a priori error estimates for the completely discretized problem of the dual mixed method for the non-stationary heat diffusion equation in a polygonal domain of R2. Due to the geometric singularities of the domain, the exact solution is not regular in the…

Improvement of wear and corrosion protection of PEO on AA2024 via sol-gel sealing

Luciane Sopchenski, Julien Robert, Matthieu Touzin, Arnaud Tricoteaux, Marie-Georges Olivier

Plasma electrolytic oxidation (PEO) is a versatile and cost-effective technique to obtain protective oxide coatings in light metals, although its intrinsic porosity is a drawback for long-term corrosion resistance. Sol-gel layers are pointed as a useful tool to seal PEO porosity and increase its…

New Developments and Biomaterials in Reconstruction of Defects of the Alveolar Ridge in Implant Surgery: Part 1—Biomaterials

Thomas Wojcik, Vincent Hornez, Jean-Christophe Hornez, Joël Ferri

Bone is a tissue that has the ability of self-regeneration leading this healing process in most of the cases to a fully morphologic and functional regeneration. However, in some situations, its healing capabilities can be surpassed, and bone grafts are frequently required for implant surgery.…

Hybrid additive/subtractive manufacturing system to prepare dense and complicated ceramic parts

Fabrice Petit, Qirong Chen, Enrique Juste, Marie Lasgorceix, Anne Leriche

As the conventional binder jetting method is limited in terms of achievable density and finish surface, a new concept of hybrid subtractive/additive manufacturing system has been recently developed. The system relies on a modified binder jetting machine which integrates a slurry-based deposition…
