摘　　要：以Cr12MoV冷作模具钢为研究对象,采用单道激光扫描与多道激光扫描相结合的方法,优化了单道激光表面淬火的工艺参数。结果表明,单道激光表面淬火下,激光功率为1 450 W时可以获得良好的硬化效果;搭接率为10%左右时,可以获得较好的搭接效果。Taking Cr12MoV cold work die steel as research object, the process parameters of single-channel laser surface quenching was optimized using the method cornbined with single-channel laser scanning and multi-channel laser scanning. The results show that the laser power of 1 450 W can obtain the good hardening effect under the conditions of the single-channel surface quenching. When the overlapping rate is about 10%, it can obtain better effect on overlapping.
