渗碳处理以气体法为主。尽管对气氛输送与控制方法已知之甚详,但还缺乏适当的模式以说明碳是如何从吸热气氛或最近发展起来的氮—甲醇混合气氛传输到被处理工件之奥氏体中去的。这就是气品公司(Air Prodncts)及其公分司(Puodair)自1977年以来从事于渗碳基本规律探讨与各气体产
Carburizing gas-based approach. Although the method of transport and control of atmosphere is well known, appropriate models are lacking to show how carbon is transported from the endothermic atmosphere or the recently developed nitrogen-methanol mixed atmosphere into the austenite of the workpiece being processed. This is why Air Prodncts and Puodair have been engaged in the basic rules of carburizing since 1977,
