利用离子氮化炉进行钢的离子渗铬。提出了离子渗铬层的形成机制，根据扩散原理提出了各种碳含量碳素钢渗铬时单相碳化物层生长动力学的计算模型，并通过实际测定与计算值进行比较，计算值与实测值非常吻合。
Ion nitriding furnace for steel ion chromizing. Based on the principle of diffusion, the calculation model of the growth kinetics of single-phase carbide layer during carburizing of carbon steel with various carbon contents was put forward. The calculated values were compared with the calculated ones The measured value is very consistent.
