According to carburizing steel's chemical composition and ore's case carbon requirements, the carbon potential of furnace inside atmosphere is controlled quantitatively.
根据所采用渗碳钢的化学成分及渗件表面合联量，对炉气联势进行定量控制。

After being treated with this technique, the disperse spheroidal carbide can be obtained in the carburizingcase 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。

The results show that the carburized case uniformity can be ensured through sand blasting or phosphating before carburizing, and NH3 is filled during carburizing.
