摘　　要：主要研究了不同激光功率对Crl2MoV钢进行激光表面淬火，分析了不同激光功率对Cr12MoV钢淬火层、显微硬度及淬火层的显微组织的影响。通过研究表明，在扫描速度V=480mm／min，光斑尺寸1mm×15mm不变的情况下，激光功率P=2100w是本试验的最佳输出功率，在此参数下所得的表层硬度可达58．9HRC，淬火层厚度大约为O．4-0．5mm。The laser surface quenching of Crl2MoV steel under different power was investi- gated and the influence of different power on the microscopic hardness and structure of the quenched layer of Cr12MoV steel was analyzed. The results show that the optimal out- put power measured is 2 100 W under the condition of scanning rate at 480 mm/min and spot size at 1 mm× 15 mm. The surface hardness under the above parameters is 58.9 HRC and the thickness of quenched layer is about 0.4mm-0.5mm.
