亚温淬火工艺在凸轮轴止推片淬火中的应用

Application of Intercritical Hardening Process for the Thrust Piece of Camshaft

对凸轮轴止推片产生淬火裂纹的原因进行了分析,提出了亚温淬火工艺,并在实践中应用,消除了淬火裂纹。

The intercritical hardening process for the camshaft thrust piece was proposed by analyzing the reason of quenching crack. The quenching crack of camshaft thrust piece was eliminated by the intercritical hardening process.
