| Abstract Scope |
Novel freeze-drying – free pressureless spark plasma sintering (FPSPS) processing sequence is developed for the production of hydroxyapatite-based micro-channeled structures. The processed specimens are characterized by scanning electron microscopy, X-ray diffraction, porosity measurements, and compressive tests. The compressive strength is different for different loading orientations. The compressive strength is higher in the loading direction parallel to the channel direction than the compressive strength in the loading direction perpendicular to the channel direction. Manipulation of freeze drying and FPSPS conditions should thereby enable the optimization of the final properties of the processed porous hydroxyapatite-based micro-channeled structures. |
