研究了激光表面强化对孕育铸铁材料组织和性能的影响。结果表明经激光处理后,其表面强度满足了HT300用于一般零件对表面硬度、耐磨性等机械性能的要求。为改进零件表面处理方法提供了依据。
The effect of laser surface strengthening on the microstructure and properties of cast iron was studied. The results show that after laser treatment, the surface strength of HT300 meets the mechanical properties of general parts such as surface hardness and abrasion resistance. To improve the parts surface treatment provides the basis.
