摘　　要：在选定45钢为主轴材料的基础上,就其热处理工艺进行了设计,通过亚温淬火渗氮工艺和传统调质工艺进行试验对比,发现45钢主轴经亚温淬火渗氮较传统调质处理在整体硬度和抗拉强度上虽稍有下降,但在表面硬度、塑性和韧度上有较大提高,满足设计要求和使用要求。In the selected 45 steel spindle material basis. The thermal treatment process design,through the intercritical hardening nitrocarburizing process and traditional hardening and tempering process of contrast test, found that the spindle of 45 steel after intercritical quenching nitriding compared with conventional quenching and tempering treatment on the hardness and tensile strength of the overall, though slightly decreased, but in the surface hardness, plastic and toughness is greatly enhanced meet design requirements and usage requirements.
