Advanced AM Titanium Materials specialist Z3DLAB Montmagny, Îl-de-France, France, and a consortium of Centre national de la recherche scientifique (CNRS) have received funding from the French National Research Agency to create complex concentrated alloys for bio-implants, or CoCoA-Bio, via Additive Manufacturing. The project will initially produce dental implant prototypes in order to validate the experimental approach.
CoCoA-bio aims to combine two innovative metallurgical concepts to provide a material solution for the increasing need of materials with both high biocompatibility and good mechanical properties. High entropy (HEA) and compositionally complex alloys (CCA), based on TiNbZr-X (X = Mo, Ta), will be fabricated via Laser Beam Powder Bed Fusion (PBF-LB).
The consortium has stated that its cross knowledge and resources on AM, the design and characterisation of HEAs and their functions will be important assets for achieving the proposal’s objectives.
