摘 要：(Zr41.2Ti13.8Cu12.5Ni10Be22.5 )100xNbx（at%, x=0 and 8） bulk metallic glasses （BMGs） were coated on the surface of Q195 steel wires by a continuous coating process. The potentiodynamic polarization tests of these BMGs were conducted in 3.5wt% NaCl aqueous solution. It is found that the addition of 8at% Nb into Zr 41.2Ti13.8Cu12.5Ni10Be22.5 alloy results in the improvement of corrosion resistance with the pitting potential of -52mV, the open circuit potential of -446mV, and the corrosion current density of 9.86×10 6 mA/cm2 . This may be attributed to that Nb is beneficial to passivate and stabilize Zr and Ti.
