Thermal oxidation effect on corrosion behavior of Zr 46Cu 37.6Ag 8.4Al 8 bulk metallic glass. Intermetallics 22 : 84-91. ScholarBank@NUS Repository. https://doi.org/10.1016/j.intermet.2011.10.013 | Abstract: | Oxide films of 0.72 μm and 1.80 μm were prepared by thermal oxidation treatments at 441 K and 609 K respectively. The oxidation kinetics of the Zr 46Cu 37.6Ag 8.4Al 8 bulk metallic glass has been investigated. The outermost surface of the oxide film formed at 609 k is Cu 2O and Al 2O 3-enriched but ZrO 2-depleted. A ZrO 2-enriched oxide layer is detected existing at 150-260 nm of the oxide film. The surface oxidation state sheds great influence on the corrosion behavior of Zr-based BMG. The oxide film can hinder the initial electrodissolution processes during polarization in 0.5 M H 2SO 4 + 0.01 M NaCl solution. The special structure and composition distribution of the oxide film lead to the modification of the BMG's corrosion behavior. © 2011 Elsevier Ltd.
