摘　　要：对自动流量平衡阀过流端帽的表面进行激光淬火研究,利用正交试验对影响激光淬火的因素进行了研究,得出激光淬火的最佳参数以及脉冲电流、扫描速度和离焦量对激光表面硬度和淬硬层深度的影响规律。试验结果表明,只要工艺参数选择适当,可获得很好的表面淬火质量,为激光加工提供了理论指导。In laser quenching research for automatic balancing valve over-current end cap surface, the factors of influence are studied on laser quenching by using orthogonal experiment. The best pa- rameters of laser quenching and the influence law on the surface hardness and hardening layer depth of layer machined by laser duing to pulse current, scanning velocity and from focal quantity are drawn. The experimental results show that as long as the appropriate laser parameters be chosen, good surface hardening quality can be obtained. These provide theoretical guidance for laser processing.
