摘　　要：通过45钢样块的激光表面淬火试验,分析了进、出端硬化层深度差异及其与激光工艺参数的关系,提出了改善硬化层均匀性的激光淬火方法—分段变速扫描。The disparity of hardening depth in the inlet and outlet ends of laser hardening surface and the influence of laser processing parameters were analyzed through laser surface hardening of 45 steel test pieces. A laser hardening method, step-by-step scanning at variable speed, to improve on homogeneity of the hardened layer, was introduced.
