| 摘 要： | 本文就CBN砂轮磨削条件下的残余应力对零件耐磨性的影响进行了较为系统的定量比较研究。试验结果表明:零件耐磨性与其表面残余应力有较强的依赖关系,当零件表面处于低应力状态(-19～-539MPa)时,零件的耐磨性最好;过大的残余压应力反而导致耐磨性降低;而当零件表面层存在残余拉应力时其耐磨性极差。

| Abstract: | The residual stresses produced in grinding with CBN wheels were comuared systemally and quantitatively with the wearability of the components, The tests have shown that the wearability of a component has a considerable dependcnce on its surface residual stress: when the residual stress on the surface is in a low stress states, the wearability is higher, and too high level of compressive residual stress causes lower wearability while tensile residual stress causes very low wearability. |
