导言本文所论述的工艺的原理在Paterson和Smith提交给1980年华孚生(Wolbson)热处理中心讨论会及后来发表在《金属热处理》1981,V.8杂志上的论文中巳论述过。作者指出,在用风扇使气氛循环的典型的渗碳炉中,输入气体的成分对于生产良好的渗碳载体并不一定是最重要的。进入的气体在未反应之前已被稀释,并且 Introduction The principles of the process discussed in this article have been discussed by Paterson and Smith in their discussion of the 1980 Wolbson Heat Treatment Center Symposium and later in the paper Metal Heat Treatment 1981, V.8. The authors note that in a typical carburizing furnace that circulates the atmosphere with a fan, the composition of the input gas is not necessarily the most important for producing a good carburizing carrier. The incoming gas has been diluted before it has reacted, and
