摘要：
The structure, thermal stability and corrosion behavior of the Ti40Zr10Cu36Pd14 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/m(2). 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 Ti40Zr10Cu36Pd14 bulk metallic glass and its partial crystalline alloys produced recently without toxic elements are expected to be applied as biomaterials.
