摘　　要：本文通过对材料为GCr15的纺锭杆进行激光淬火工艺研究以提高纺锭杆的耐磨性。提出了用三点淬火法来对纺锭杆的前端进行激光淬火,这种方法改善了纺锭杆工作时的润滑条件。通过实验分析得出了GCr15材料最佳的激光淬火工艺参数,以保证纺锭杆前段能够达到最高的硬度。并针对较高淬火温度下,表面硬度下降现象进行了试样的金相分析,找出了产生这种现象的原因。In order to improve the lifespan of hasp pole, the method using laser to quench hasp pole made of GCr15 are pat forward in this paper. Through experiment, three points method of laser quenching to hasp pole is used to improve the lubricating enviroment of hasp pole. many experiments are done to find the optimized laser quenching technology parameters which can make the hardness of the quenched area of hosp pole hight：. In the laser, analyzing the metallography of the special sample whose surface hardness is lower when the quenching temperatore is higher, and the reason is found.
