This paper deals with the study on the combined treatment of ion nitrocarburizing ion sulphurizing of W18Cr4V steel The experiment showed that the compound layer with nitride and sulphide is obtained in surface of W18Cr4V steel by the combined treatment of ion nitrocarburizing and sulphurizing The compound layer greatly improves the wear resistance of W18Cr4V stee

本文研究了Ｗ１８Ｃｒ４Ｖ钢的离子氮碳共渗－离子渗硫复合处理工艺。

The experimental result shows that sulfuring rate from coke to hot metal reduces with witherite and CaCl2 addition in coke making, but the sulfuring rate increased with lime stone.

结果表明,在实验条件下,加入毒重石和CaCl2的焦炭能降低焦炭向铁水渗硫率,减少进入铁水中的硫含量;而加入石灰石的焦炭中硫进入铁水中含量较多。
