摘　　要：针对内齿圈表面硬度、耐磨性以及疲劳强度不足的问题,在其表面渗氮以增强其表面性能。在对渗氮方式和气体渗氮设备及工艺进行说明的基础上,重点对渗氮温度、氮势、渗氮时间等参数对内齿圈渗氮层脆性和耐磨性的影响进行研究,对后续指导并提升内齿圈渗氮层的性能具有理论意义。To address the problems of insufficient surface hardness,wear resistance and fatigue strength of the inner gear ring,nitriding is carried out on its surface to enhance its surface properties.Based on the analysis of nitriding method and gas nitriding equipment and process,the effect of parameters such as nitriding temperature,nitrogen potential and nitriding time on the brittleness and wear resistance of nitriding layer of internal gear ring is studied,which has theoretical significance for the subsequent guidance and improvement of the performance of nitriding layer of internal gear ring.
