Bulk metallic glasses (BMGs) of Zr65Cu17.5Ni10Al7.5, (Zr60Nb5)Cu17.5Ni10Al7.5 and (Zr60Nb5)Cu17.5(Ni5Pd5)Al7.5 were prepared by copper mold casting. The corrosion behavior of the BMGs in different types of artificial body fluids, including artificial salvia solution (ASS), phosphate buffered solution (PBS) and artificial blood plasma solution (ABP), was investigated by electrochemical polarization and galvanostatic-step measurements at a constant temperature of 37 °C. It was found that all three BMGs exhibited excellent corrosion resistance in various artificial body fluids. Compared with Zr65Cu17.5Ni10Al7.5 base system, the BMGs containing Nb, or Nb and Pd, exhibited superior corrosion resistance against pitting, indicating that the addition of Nb enhanced the corrosion resistance.
