摘　　要：对20CrMnTi钢半轴齿轮渗碳淬火回火后硬化层深浅不一现象进行了研究。通过控制渗碳井式炉内上下温差、严格执行渗碳工艺、改进淬火回火工艺等措施,有效控制了硬化层深度,保证了半轴齿轮质量。The phenomenon of different shades of hardened layer after carburizing quenching and tempering of 20 CrMnTi steel semi-axle gear was investigated.By controlling the temperature difference between the upper and lower sides of the carburizing pit furnace,strictly implementing the carburizing process and improving the quenching and tempering process,the depth of the hardened layer is effectively controlled and the quality of the semi-axle gear is ensured.
