对腐蚀后试样表面产生的氧化膜分别进行显微结构、物相、成分等分析。采用NANO SEM400扫描电子显微镜(SEM)及附带的能谱系统(EDS)观察氧化表面膜形貌,分析氧化膜成分
The microstructure, phase and composition of the oxide film were analyzed respectively. NANO SEM400 scanning electron microscope (SEM) and energy dispersive spectroscopy (EDS) were used to observe the morphology of the oxide surface film and analyze the composition of the oxide film.
