摘要： 将45钢激光淬火强化处理区域再进行激光冲击强化处理。处理结果表明：复合强化处理后的45钢与经激光淬火强化处理区域相比，其硬度和耐磨性能都得到了很大提高，其中，硬度提高了15%，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。

关键词: 残余应力, 激光冲击, 激光淬火, 耐磨性, 硬度

Abstract: It is studied that the hardened zones of 45 steel are processed through laser shock again, after laser quenched. The results indicate that properties of the zone treated through compound method is improved, compared to that through only laser quenched . The hardness increases by 15% and the wearability enhances 100%. Especially, the residual stress of the interior of the material is changed into com-pressive stress.

Key words: Residual stress, Hardness, Laser quenched, Laser shocked, Wear-resistance
