碳钢表面激光TiN合金化的研究

Study of TiN laser alloying in the carbonic steel surfaces

本文介绍了用一台CO_2激光器对碳钢表面进行了TiN激光合金化处理,对处理后的合金层的组织结构、相形貌、合金元素的分布、硬度和耐磨性能进行了测试和分析,结果表明:TiN激光合金化使45~＃钢基体产生了多种强化效果。

The experimental Procedure for the TiN laser alloying in the carbonic steel surface by using a CO_2 laser is described. A compre- hensive analysis of the phase structure, the phase morphology, the distribution profile of the alloying elements, the hardness, and the resistance to abrasion of the alloyed layer after laser treatment is in- troduced. The results indicate that TiN laser surface alloying will give many strengthening effects on the carbonic steel surface. The charac- teristic of the base metal surface can be greatly ameliorated.
