| 摘 要： | 用（L93^4）正交试验法研究QT600-3凸轮轴激光相变硬化工艺参数优化组合，分析了凸轮轴激光相变硬化方法。试验结果表明：激光相变硬化层显微硬度比等温淬火提高了50％；硬化层深达0．5mm；耐磨性提高了1倍；表面残余应力为压应力。能满足凸轮轴工作要求，为改进凸轮轴表面处理方法提供了依据。

| Abstract: | The paper deals with the results on processing parameters of laser transformation hardening for QT600-3 camshaft by using (L_9 3~4 ) orthogonal experiment . The results shows the surface hardness of laser transformation hardening is 50 percent more than that of isothermal hardening the hardened depth is about 0.5mm; the wear-resistance increases one double; especially, the residual stress of the interior of the material is changed into compressive stress. The experimental results provide a basis to improve the surface properties of camshaft. |
