Compressive Property and Electrochemistry Behavior of Porous Ti-Nb-Ta-Zr for Biomedical Applications

摘要

Porous Ti-Nb-Ta-Zr alloys for biomedical applications were successfully fabricated by PM. The microstructure, cycle compressive and electrochemistry behavior were studied. It results that the porous structure of Ti-Nb-Ta-Zr with 0.8 GPa Young's modulus, 2.7% pseudoelastic strain ratio and -0.44 V corrosion potential in SBF, can be applied to the trabecular bone prosthesis or bone substitute for spinal vertebral body.
