COXEM台式扫描电镜在材料学中的应用-金属材料

Above image is a copper sample coated with nickel and gold. Since nickel and copper have similar atomic number, it is hard to differentiate the boundary between the two. Through chemical etching, as shown in the right image, two layers can be easily distinguished. If etching is impossible, layers can be distinguished in the BSE mode. 库赛姆（COXEM）EM-30 Plus台式 扫描电镜
