The structure of spheroidalcarbide in wear resistant white iron was investigated by SEM observation and EPMA of ion etched metallographic specimen.
用离子蚀刻加扫描电镜观察和微区成分分析的方法研究了耐磨白口铁中球形碳化物的结构。

After being treated with this technique, the disperse spheroidalcarbide can be obtained in the carburizing case which is superior to that by normal carburizing in properties.
经该工艺处理后渗层可获得弥散碳化物,其性能大大优于常规渗碳。
