摘要
将激光淬火强化处理后的40Cr钢的强化区域再进行激光冲击强化处理,处理结果表明,复合强化处理后40Cr钢与经激光淬火强化处理区域相比,各项机械性能都得到了大幅提高,其中,硬度提高了10.9％,耐磨性提高了100％,尤其是材料内部残余应力全部变成了残余压应力。
It has been studied that the hardened zonesof 40Cr steel are processed through laser shock again af-ter laser quenched. The results indicate that properties ofthe zone treated through compound method are improved,compared to that through only laser quenched. The hard-ness increases by 10.9% and the wear -- resistance en-hances 100%. Especially, the residual stress of interiorof the material is changed into compressive stress.
