Bio-properties of Zr-based BMGMC as potential hard tissue implants
In this study,an in situ formed bulk metallic glass matrix composite (BMGMC) (Zr58.5Ti14.3Ni4.9Cu6.1Nb5.2Be11.0) was synthesized.Bulk metallic glass (BMG) (Zr52.5Cu17.9Ni14.6Al10.0Ti5.0) was also included in this work and a Ti-6Al-4V alloy was used as a reference material.Due to the glassy matrix that postpones the growth of corrosion pits,the BMGMC displays high positive corrosion potentials and low corrosion current densities.The BMGMC exhibited a higher improved corrosion resistance than the Ti alloys.Furthermore,the biocompatibility of this BMGMC was assessed by studying the cellular behavior of bone-forming mouse M3T3-E1 pre-osteoblast cells.The matrix did not significantly affect cell adhesion,proliferation and ALP activity.The general biosafety of Zr-based BMGMC for M3T3-E1 cells was revealed as normal cell responses.Zr-based BMGMC shows great potential for applications in the hard tissue implants.
