Abstract
In this study, we compared the bio-corrosion resistance and biocompatibility of a ZrTi -based BMGMC ( Zr 58.5 Ti 14.3 Ni 4.9 Cu 6.1 Nb 5.2 Be 11.0). The Ti - 6Al - 4V alloy was used as a reference material. By utilizing the electrochemical measurements and M3T3 cell culture, the corrosion resistance and biocompatibility of this BMGMC were evaluated. The BMGMC displayed high positive corrosion potentials and low corrosion current densities, which indicated that this material exhibited a highly improved corrosion resistance than the Ti alloy. The cells could adhere on the surface of this BMGMC and exhibited improved cellular behaviors, such as cellular viability and cytoskeketal structure. In summary, the ZrTi -based BMGMC showed great potential for applications in the hard tissue implants.
