快速固体渗碳及应用

Process and Application of High Speed Pack Carburizing

本文研究了大剂量碳酸盐催渗剂对20、20Cr、18CrMnTi钢固体渗碳过程的影响。结果表明,与常规固体渗碳相比,渗速提高3～4倍。用于处理中低碳钢制作的冲裁模具,效果良好。

This paper deals with the effect of much carbonate catalyst on the pack carburizing processes of the 20Cr、18CrMnTi、20 steel. The results shown that the diffusing rate can be increased by 3～4 times comparing with pack carburizing processes, The method is applicable in treating the blanking and punching die made of medium-low carbon steel and achieve good results.
