本文叙述了45钢表面激光铬钼合金化形成过程,分析了用均匀矩形激光束和圆形激光束硬化不均匀的原因。通过后续工艺处理,可以改善表面层的组织和性能。本文还讨论了激光合金化的强化机理。
This paper describes the formation of laser chrome-molybdenum alloying on the surface of 45 steel, and analyzes the reasons for the uneven hardening with a uniform rectangular laser beam and a circular laser beam. Through the follow-up process, you can improve the surface layer of the organization and performance. This article also discusses the strengthening mechanism of laser alloying.
