摘要：

Characterization of Zr-based bulk metallic glass (BMG) corroded by spout electroanalysis was investigated by transmission electronic microscopy (TEM) and energy depressive X-ray spectroscopy (EDS) analysis. Results show that during the spout electroanalysis corrosion process, the nanocrystallines in the amorphous region are corroded more easily than bulk metallic glass. In addition, there are some special amorphous regions in the amorphous specimens by electroanalysis corrosion of perchloric acid solution in alcohol, where a lot of amorphous oxides were observed, and Ni content decreased. The region formation was resulted from nano-pitting of chlorine ion.
