“…6a, c, and e). The background currents were usually retained in tens of nano-amperes (nA) with an acceptable variation [28,29]. Many current transients, which are characterised by a sharp rise followed by a slow decay in the current, can be detected on the 316L SS (Fig.…”

“…Several studies on aqueous corrosion of glass-forming alloys, e.g. FeCSiBPCrAlMo [11], NiNb [12] and ZrCuNiAlTi [13], suggested an enhanced corrosion resistance on structurally relaxed metallic glasses as indicated by the significantly improved passivation behaviours. Ni-Nb-Ti-Zr-Co bulk metallic glasses possess not only high glass-forming ability but also extremely high corrosion resistance and good mechanical properties [14][15], which are promising materials for the applications in extremely aggressive solutions.…”

Electrochemical corrosion behaviours of as-spun, as-cast, and relaxed Ni 55 Nb 20 Ti 10 Zr 8 Co 7 metallic glasses were investigated in 3 mass% NaCl and 1 N H 2 SO 4 solutions in order to study the effect of different amorphous microstructure. Static immersion tests indicate that the as-spun ribbon possesses the most active state in the NaCl solution at its open circuit potential, followed by the as-cast rod, the relaxed ribbon, and the relaxed rod. While in the H 2 SO 4 solution, the rod samples are more stable than the ribbons, and the relaxed samples exhibit higher stability than the as-quenched samples. The polarization tests revealed slightly higher passive current density (i pass ) for the ribbons than those of the rods in both electrolytes, although no significant differences in i pass were found between the relaxed and the as-quenched specimens. It is concluded that electrochemical corrosion behaviours of metallic glasses are related to the amorphous structure, and a decrease in free volume generally favors corrosion resistance.
