| Abstract: | Fe55Ni2Cr12Mo10B6C13Y2，Fe55Cu2Cr12Mo10B6C13Y2 and Fe55Nb2Cr12Mo10B6C13Y2 alloys with diameter of 4mm were produced by copper mold casting. The role of alloying additions (Ni, Cu or Nb) on corrosion resistance of Fe55Nb2Cr12Mo10B6C13Y2, Fe55Ni2Cr12Mo10B6C13Y2 and Fe55Cu2Cr12Mo10B6C13Y2 alloys were studied by polarization curves and electrochemical impedance spectroscopy (EIS). The results show that Fe55Ni2Cr12Mo10B6C13Y2 and Fe55Cu2Cr12Mo10B6C13Y2 alloys can be cast into bulk metallic glasses. Fe55Ni2Cr12Mo10B6C13Y2 and Fe55Cu2Cr12Mo10B6C13Y2 amorphous alloys with passive potential about 1500 mV exhibit good corrosion resistance in 5 % NaCl solution and 1 mol/L HCl solution. The passive current density of the alloy with Ni addition is lower than other alloys. EIS results only show one impedance element. Amorphous alloy Fe55Ni2Cr12Mo10B6C13Y2 with larger charge transfer reaction resistance indicates good corrosion resistance. |
