摘要
利用表面激光熔覆技术对高锰钢试样进行了不同工艺条件的表面强化处理,对其组织和表面硬度进行观察和测试,并对其中一组结果最为理想的试样进行了熔覆层显微硬度、耐磨性及TEM分析。结果表明:激光熔覆层的硬度、耐磨性较高锰钢基体均有大幅度提高,在熔覆层与基体的过渡区内,局部存在非晶组织。
The surface strengthening treatment of high-manganese steel specimens under different process conditions was carried out using laser cladding process.The microstructure and hardness of the coating were observed and tested.The microhardness and wear resistance of the coating were analyzed,and the microstructure was observed by TEM.The results show that the hardness and wear resistance of the coating are improved remarkably.In the transition zone,there is amorphous microstructure in local part.
