| 摘 要： | 利用透射电子显微镜(TEM)及场发射电镜纳米尺度成分分析技术(EDS分析)研究块状非晶Zr_(70)Cu_8Ti_7Ni_(15)喷射电解腐蚀特征.结果表明:在喷射电解腐蚀过程中,非晶内少量纳米级别的晶体相对于块状非晶基体较容易被腐蚀破坏.此外,经高氯酸乙醇溶液电解腐蚀后非晶中明显存在一些特殊非晶区域,其中含有大量非晶态氧化物,Ni大量流失,这些区域的形成是由于Cl离子点蚀引起的. |

| Abstract: | 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. |
