| 摘 要： | 采用电化学方法研究了块体Mg65Cu25Gd10非晶合金在0.01 mol/L,pH=13的NaCl溶液及0.1 mol/L,pH=13的NaOH溶液中的腐蚀行为.在2种电解质溶液中,非晶合金样品的极化曲线具有明显的钝化区和较低的钝化电流密度.浸蚀样品的表面形貌和腐蚀产物采用SEM和EDS来表征.恒电位钝化后样品表面层化学信息运用DP-XPS来考察.结果表明,样品在NaOH溶液中形成致密少孔的钝化膜,而在含Cl离子的溶液中,样品表面钝化膜疏松且多孔,导致合金在含Cl离子的溶液中具有较低的耐蚀性.

| Abstract: | The corrosion behavior of bulk amorphous Mg65Cu25Gd10 alloy was studied by electrochemical measurement. The potentiodynamic polarization tests were carried out in 0.01 mol/L NaCl solution and 0.1 mol/L NaOH solution with pH=13. The amorphous Mg65Cu25Gd10 alloy was spontaneously passivated at a significantly low passivation current density in the two kinds of solutions. The surface morphology and corrosive products of samples after dipping tests were characterized by scanning electron microscopy (SEM) and en... |
