Laser Powder Bed Fusion Processing Of Complex Concentrated Alloys For Bio-Implants

Élaboration d'un alliage concentré complexe par fusion laser sur lit de poudre pour la fabrication de bio-implants

Résumé

As the population ages in modern societies and the risks of bone diseases or bone accidents increase, there is a need for a new generation of materials with superior biocompatibility and good mechanical properties. This study combines two innovative metallurgical concepts to provide a material solution for the intended application. To this end, multicomponent and complex concentrated alloy (HEA/CCAs) based on TiNbZr-X (X = Mo, Ta) system is fabricated via additive manufacturing (AM), namely by Laser-Powder Bed Fusion (L-PBF) of gas-atomized pre-alloyed powder. After each stage of development by L-PBF through Taguchi's design of experiments, complete microstructure characterization and mechanical behavior of the resulting samples under different loading conditions are conducted. In addition, mechanical surface functionalization carried out by machining with metrological monitoring as a pre-step before a chemical functionalization for the suitability of materials developed for the intended application.
