摘　　要：本文介绍了一种新型渗碳工艺，研究表明：利用高温强渗，较高温次平衡碳势扩散、预冷淬火的渗碳方法，可有效地提高渗碳速度，改善渗层组织，消除渗碳磨削裂纹。不同阶段的渗剂中，配以不同比例的水，可消除工件表面碳黑，有利于控制炉气碳势，实现反扩散，获得良好的渗层碳浓度梯度。This paper introduces a new kind of carburizing technology.The study proves that utilizing high temperature reinforcing carburizing,higher temperature sub balance carbon potential diffusion and pre cooling quenching can effectively increase the speed of carburizing improve diffusion layer structure and eliminate carburizing grinding crack.When carburizing agents at different stages are mixed accordingly with water of different proposition,the carbon black on workpiece can be removed,which can be useful for controlling gas the carbon potential, and therefore anti diffusion is realized and a better carburizing layer carbon gradients obtained.
