摘要
采用CO2激光器对34CrNiMo汽轮机齿轮进行了表面淬火修复处理,探讨了加工功率和扫描速率对淬硬层厚度、金相组织和淬硬层硬度的影响。结果表明,当扫描速率为1000mm/min时,随着淬火功率的增大,淬硬层深度增加明显;淬硬层组织明显细化,硬度可以达到HV670。
The laser quenching repair of the surface 34CrNiMo gas turbine gear was carried by CO2 laser. The effect of laser power and scanning velocity on hardened depth, mierostrueture and hardness values of the laser quenching layers was analyzed. The results indicate that when the value of scanning velocity is 1000mm/min, the values of hardened depth are increased obviously with increasing of power. The microstructure of the quenched layers is refined and the max hardness value is HV670.
