金属和合金表面的激光强化,关系到能否在表面层形成一些具有较高的、有时是独特的机械性能的组织。激光合金化是一种有发展前景的强化金属和合金的新方法。在激光合金化的过程中被处理材料表面层的化学成分发生变化。一些著作中在激光渗氮合金化后观察到钢的机械性能有所提高,但是对这个问题研究得不充分,还需要作补充的研究。 Laser strengthening of metal and alloy surfaces is related to the ability to form on the surface layer some higher, sometimes unique, mechanical properties of the tissue. Laser alloying is a promising method of strengthening metals and alloys. The chemical composition of the surface layer of the material being processed changes during laser alloying. In some works, the mechanical properties of steel have been observed after laser nitriding. However, the study of this problem is not enough, and further research is needed.
