渗碳气氛中碳势理论表达式及精确测定

The Theoretical Expression of Carbon Potential for Carburizing Atmosphere and Its Exact Measurement

论述了渗碳气氛中碳势的意义及影响因素，根据渗碳反应热力学与传质动力学的基本理论推导了碳势的准确表达式，并据此得出了快速、精确测定碳势的新方法。

The paper deals with the signification of carbon potential and its influencefactors. The exact expression of carbon potential has been deduced on the basis of reactionthermodynamics and masstransfer kinetics for carburization,and according to these a new methodto measure carbon potential quickly and exactly has been suggested.
