Element-specific in situ corrosion behavior of Zr-Cu-Ni-Al-Nb bulk metallic glass in acidic media studied using a novel microcapillary flow injection inductively coupled plasma mass spectrometry technique

Moreover, X-ray photoelectron spectroscopy (XPS) was employed to characterize the composition of the oxide film before and after the immersion in acidic corrosive medium. Based on microcapillary FI-ICP-MS and XPS results the mechanisms for simultaneous Al and Cu depletion and Zr content enrichment in the oxide film were proposed.
