In comparison to monolithic Ti-based BMGs and Ti-6Al-4V alloy, the in-situ BMG matrix composite with similar to 20% volume fraction of beta-(Ti,Zr,Nb) phase exhibits a high corrosion resistance characterized by a low value of corrosion current density, a stable passivation behavior in both potentiodynamic and potentiostatic polarization and low weight loss during immersion tests. The enhancement of the corrosion resistance is attributed to Ti-, Zr- and Nb-rich oxide layers produced on top of both the dendrite and amorphous matrix. However, for the BMG composite with a large (similar to 41.5%) volume fraction of Nb-rich dendrites the corrosion resistance was reduced leading to the dissolution of the amorphous matrix during immersion tests.
