| 摘 要： | 对经激光淬火强化处理后的球墨铸铁QT800-2的强化区域再进行激光冲击强化处理进行了研究。结果表明,复合强化处理后的球墨铸铁QT800-2与经激光淬火强化处理区域相比,各项机械性能都得到了较大提高,其中硬度提高了18％,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。

| Abstract: | In this paper, it has been studied that the hardened zones of ductile iron QT800-2 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 18% and the wearability enhances about 100%. Especially, the residual stress of the interior of the material was changed into compressive stress. |
