| 摘 要： | 研究了稀土氮碳硼共渗对45钢疲劳性能的影响。结果表明，稀土氮碳硼共渗处理后，45钢疲劳寿命显著提高，裂纹形成延迟，裂纹扩展速度降低。表面出现残余压应力和表面硬度提高是稀土氮碳硼共渗处理改善45钢疲劳性能的主要原因。

| Abstract: | The influence of RE N C B diffusion process on the fatigue properties of 45 steel was investigated.The results show that the life of fatigue is increased remarkably,the period of crack initiation is delayed and the propagation rate of crack is decreased after RE N C B diffusion of the steel.The mechanism to improve the fatigue properties are the residual compression stress and the increase of the surface hardness. |
