| 9. | The network carbide and acicular martensites that existed in the microstructure of the root grooves of the spline due to improper carburating and quenching process of the shafts , led to the initiation and propagation of the intergranular microcracks and were the main reason that caused the early fracture of the shafts
由于渗碳淬火工艺不当，在二轴花键槽根部的组织中产生了网状破化物和粗大的针状马氏体，在外力作用下形成沿晶显微裂纹并扩展，是导致二轴疲劳断裂的主要原因。 |
| 10. | It is shown from results that increasing carburizing time further in the normal technology can not obviously deep the carburizing layer , but can cause nonmartensite microstructure at the bottom of the gear and coarse grain across the gear , these will heavily decrease the fatigue life of the gear
结果表明：在正常渗碳淬火工艺基础上再延长渗碳淬火1小时，齿轮渗碳层深度变化不大，但其齿根局部表面处有非马组织，且晶粒尺寸易产生异常长大现象，从而致使台架疲劳寿命明显下降。 |
