真空渗碳是在近似真空但存在部分碳氢气分压中一种不平衡的强渗/扩散型渗碳过程。本文的第二部分是C.I.Hayes公司在它的工业热处理设备上对渗碳气体循环和高温热处理过程(在950℃以上)进行了四年多研究结果的评论。对渗碳气体的组成和热处理模拟试验的研究结果也作了评论。
Vacuum carburizing is an imbalanced intensive infiltration / diffusion carburization process in a near-vacuum with partial pressure of partial pressure of hydrocarbons. The second part of this article is a review by C.I. Hayes for more than four years of research on carburizing gas circulation and high temperature heat treatment (above 950 ° C) on its industrial heat treatment equipment. The composition of the carburizing gas and heat treatment simulation results of the study also made a comment.
