| 摘 要： | 研究了20CrMnTiH钢同步器齿毂经真空低压渗碳热处理后组织和性能的变化,并与气氛渗碳热处理工艺进行对比。结果表明,真空渗碳热处理后齿面位置处几乎无晶间氧化和非马氏体组织,在晶间氧化的控制上较大幅度优于气氛渗碳热处理工艺;高压气淬在齿毂类零件的热处理畸变控制方面优于油液淬火。

| Abstract: | The changes of microstructure and properties of 20CrMnTiH steel synchronizer gear hub after vacuum low pressure carburizing heat treatment were studied and compared with that by atmosphere carburizing heat treatment process. The results show that there is almost no intergranular oxidation and non-martensitic structure after vacuum carburizing heat treatment, and the control of intergranular oxidation is much better than that of atmosphere carburizing heat treatment. High pressure gas quenching is superior to oil quenching in heat treatment distortion control of the gear hub. |
