摘要
通过试验,分析了GCr15钢经激光相变强化后硬化层的微观相结构;验证了经过激光相变强化后其表面硬度可得到明显提高;探讨了激光相变强化提高GCr15钢表面硬度的机理。
This paper analyzes the microstructure of the hardened layer of GCr15 steel after laser phase-change hardening,which shows that the surface hardness is raised obviously. It also discusses the mechanism of using laser phase-change hardening to improve the surface hardness of GCr15 steel.
