孕育铸铁激光表面强化研究

Study on Laser Surface Hardening of Inoculated Cast Iron

研究了激光表面强化对孕育铸铁组织和性能的影响。结果表明 ,HT30 0零件激光处理后可满足表面硬度、耐磨性等力学性能的要求 。

This paper deals with the effect of laser surface hardening on microstructure and properties of inoculated cast iron HT300.The experimental results showed that the surface strength could satisfy the mechanical properties requirements for general components using HT300,such as surface hardness and wearability.The results also provide a basis for improving the surface properties of components.
