摘要
从动力学角度研究了气体渗碳过程中表面碳浓度增长的规律;得出了气体渗碳过程属于界面反应和扩散的混合控制型的结论;讨论了碳传递系数β值的测定。
The increasing rules of surface carbon concentration in gas carburization is studied from the view of dynamics.The view point is proven,which indicates that gas carburization process is controlled by interfacial reaction and diffusion together.The measurement of carbon transfer coefficient β is discussed in the paper.
