Abstract

Ni₅₅Nb₃₀Sn₅Ti₅Zr₅ and Ni₅₅Nb₃₀Sn₅Zr₁₀ bulk metallic glasses with the partially crystallized structure were prepared by water-cooled copper-mold casting. The microstructures of the two alloys were investigated by means of XRD. The corrosion behavior of the alloys in 1 M NaCl and 1 M NaOH aqueous solution at room temperature was investigated by potentiodynamic polarization and immersion methods. The surface morphology after corrosion in 10% HCl solution was observed by SEM. Both Ni-based alloys exhibited spontaneous passive behavior in the selected electrolytes. The partially crystallized alloys had higher corrosion resistance in comparison with the fully amorphous alloy. Ti-addition to Ni₅₅Nb₃₀Sn₅Zr₁₀ alloy can improve the corrosion resistance due to the formation of Ti oxides.
