| 摘 要： | 对42CrMo钢进行不同参数下的激光淬火处理,研究了激光淬火功率和扫描速度对42CrMo钢表面淬火硬度和淬火深度的影响规律,分析了在激光功率密度为定值时不同激光淬火参数下硬化性能的变化趋势。研究结果表明,激光功率的增大和扫描速度的减小均可以提高淬火层的深度和硬度;结合激光功率和扫描速度计算所得的能量密度参数与淬火效果存在较强相关性,在能量密度相同时,高功率高速度参数可以增加淬火硬度和深度,并提高加工效率。

| Abstract: | Influence of laser quenching power and scanning speed on surface hardness and hardened depth of the 42CrMo steel was studied by applying different process parameters, and the variation trends of hardening performance under constant laser energy density and different laser quenching parameters were analyzed. The results show that the hardened depth and hardness of the hardened layers can be improved by increasing laser power and decreasing scanning speed. There is a stronge correlation between the energy density parameters calculated by combining the laser power and scanning speed and the quenching effect. Under the same energy density, the high power and high speed parameters can increase the hardness, hardened depth and processing efficiency. |
