Abstract

The structure, thermal stability and corrosion behavior of the Ti ₄₀Zr₁₀Cu₃₆Pd₁₄ bulk metallic glass and its crystalline alloys have been investigated in this paper. The results of potentiodynamic polarization measurements revealed that the Ti-based bulk metallic glass and its crystalline counterparts examined were spontaneously passivated by anodic polarization with the passive current density about 10 ^-2 A/m². The higher corrosion resistance for the Ti-based bulk metallic glass and partly crystalline alloys was attributed to stable and protective passive films enriched with titanium and zirconium. The Ti ₄₀Zr₁₀Cu₃₆Pd₁₄ bulk metallic glass and its partial crystalline alloys produced recently without toxic elements are expected to be applied as biomaterials.
