摘要
介绍采用热化学共渗法对硬质合金拉丝模芯进行超硬化处理，以提高其表面硬度的方法。通过生产性试验探索出具有实用价值的共渗剂配方及最佳的共渗工艺。
The article introduces the method of superhardening treating hard alloy drawing die core with thermochemistry copermeation method so as to improve its surface hardness. The copermeation agent prescription and the best copermeation technology with practical value have been explored out by production experiment.
