摘要
综述了激光表面改性技术在热作模具钢表面改性中的应用现状;介绍了激光相变硬化、激光熔凝、激光合金化及激光熔覆对热作模具钢表面组织结构和性能的影响,并对热作模具钢激光表面改性技术进行了展望。
The research status of laser surface modification on hot working die steel was mainly discussed. The effects of laser hardening, laser melting, laser alloying and laser cladding on the microstructure and property of hot working die steel surface were introduced. In addition, the prospect of laser surface modification on hot working die steel was outlooked.
