Description |
This paper reports the changes in the electrochemical behavior of Cu 60 Zr 25 Ti 15 bulk metallic glass (BMG)
with the addition of 1 at.% Mo and Nb in 3.5 wt.% NaCl aqueous solution. Electrochemical methods
employed for the study are open-circuit potential (OCP) and potentiodynamic polarization. The OCP
values of the parent BMG and minor-alloyed BMGs differ only marginally. However, potentiodynamic
studies show slightly higher corrosion resistance for the minor-alloyed BMGs than that of the parent alloy.
Polarized surfaces of all the samples, examined under a scanning electron microscope (SEM), reveal pits
formed due to corrosion. Corrosion products are analyzed by energy-dispersive spectroscopy (EDS) and X-
ray photoelectron spectroscopy (XPS). Higher corrosion resistance observed for Nb- or Mo-added BMGs is
attributed to the formation of NbO 2 /Nb 2 O 5 and MoO 2 , respectively, besides the oxides of other constituent
elements.
