| Outline of Final Research Achievements |
Implant treatment has been widely applied to restore bones and teeth damaged by aging and injury, and it is important issues to develop implant materials with high biocompatibility and mechanical properties. This research dealt with fabrication of biocompatible functionally graded materials (FGM) considering creation of biomaterials-interphase in spark plasma sintering (SPS). By using four kinds of materials, partially stabilized zirconia (PSZ), Alumina (Al2O3), pure titanium (Ti) and stainless steel (SUS316L), (1) fabrication and evaluation of PSZ-Ti and Al2O3-Ti composites and FGMs, (2) creation mechanism and mechanical properties of biomaterials-interphase, and (3) mechanical model to analyze three-phase composites and FGMs were investigated. It was found that sinterability and mechanical properties of FGM were strongly influenced by the combination of materials.
