Unexpected facture without any room-temperature plasticity severely limits potential structural applications of bulk metallic glasses (BMGs), especially La-, Mg- and Fe-based ones. In this study, a simple free corrosion method was provided to improve the plasticity of a brittle (La, Ce)-based BMG by...

用光电化学方法研究了Cu在不同浓度NaCl的硼酸--硼砂溶液中的腐蚀以及缓蚀剂聚天冬氨酸(PASP)对Cu的缓蚀作用. Cu在硼酸--硼砂缓冲溶液中, 表面的Cu2O膜为p型半导体. 当Cu所在的溶液中存在少量NaCl (小于0.5 g/L)时, Cu表面Cu2O膜会受轻微Cl-掺杂但不会改变半导体...

通过电化学阻抗谱(EIS)技术研究了LY12铝合金/钝化膜/环氧涂层复合电极在NaCl水溶液中的腐蚀行为.结果表明, 随浸泡时间的延长, 复合电极体系的阻抗不断增大;在浸泡初期, 复合电极体系的阻抗谱中即出现了低频扩散阻抗, 认为该阻抗由金属表面钝化膜的溶解产物的传质引起. 扫描电镜(SEM)观察表...

Al-alloy (AA5022) corrosion penetration (CP) and crystal structure were investigated after running static immersion corrosion tests in 1 mol/L HCl solution and different concentrations of rare earth elements (La3+), (Ce3+) and their combination, at different temperatures. X-ray diffraction (XRD) was...

A cellular automata model was used to study the diffusion characteristics in the corrosion film at a mesoscopic scale. The model focused on a metal/film/electrolyte system, including a series of local evolution rules. The effect of diffusion rate on the film growth and metal corrosion was investigat...
