| 中文摘要: |
| 为了使钢结硬质合金制成的冷作模具的使用寿命进一步提高，研究了一种硼-硫共渗强化新工艺，试验结果表明，渗硼模具的使用寿命比未渗硼模具提高了10多倍，硼-硫复合渗透模具的使用寿命又比单一渗硼模具提高了50%~70%。 |
| 英文摘要: |
| In order to increase the service life of cold working steel bonded carbide dies, a new process of surface boronizing and sulfurizing is developed. The experiments show that the service life of boronizing dies are increased more than 10 times compared with non-boronizing dies, and the service life of boronizing and sulfurizing dies are increased by 50%~70% compared with boronizing dies . |
