摘　　要：本文列举了蒸汽处理、高速钢工具氧氮化处理和氧碳氮共渗工艺、表层组织和结构,以及对使用性能的影响。在软氮化和氮化时添加适量的氧能加速化学热处理过程。The present paper lists the processes ot vapour treatment, oxygen-nitriding treatment and oxygen-carbonitriding of high speed tool steels, their surface structures as well as their effects on the use properties. Proper addition of oxygen during the tufftriding and nitriding can accelerate the process of chemical heat-treatment.

关 键 词：氧化 氧碳氮共渗 化学热处理
