【摘要】 采用扫描电镜、能量色散谱和俄歇电子能谱检测方法 ,对银币表面缺陷进行了分析。结果表明 ,在银币缺陷部位的腐蚀坑内存在以铁元素为主的物质 ,基材中的铁元素与外界的氯引起银币的腐蚀 ,造成了表面缺陷。更多还原

【Abstract】 The surface defects of silver coins was analysed with auger electron spectroscopy (AES), Scanning electronic microscope (SEM) and energy dispersive spectrum (EDS). The results indicated that the defects was caused by pitting corrosion of impurity element iron in silver coin by environmental chloride compound.更多还原
