| 摘 要： | 针对传统的“先成形，后渗碳”工艺在硬齿面齿轮渗碳层厚度分布和组织形态方面存的问题，提出齿轮“渗碳一温挤”成形新工艺。实验结果表明，通过调整模具结构(模具圆角半径等)、合理选择成形工艺参数(成形温度等)，可使齿轮渗碳层厚度分布合理、组织改善(晶粒细化)。 |
| 关 键 词： | 硬齿面齿轮 渗碳 渗碳层组织 渗碳层厚度 温挤压 |

| Abstract: | The disadvantageous factor of carburized-case depth distribution and microstructure for hardened gears in the process of carburizing after manufacturing was analyzed. A technical approach of Warm Forming after Carburizing was put forward. The experimental results show that it can make Carburized-Case distribution suitably and its microstructure improvements(e.g. grain refining) by adjusting shape of the die(e. g. die radius) and selecting appropriate parameter of the process variable(e. g. forming temperature). |
| Keywords: | surface hardened gear carburized case microstructure carburized-case depth distribution warm forming |
