摘　　要：利用激光表面强化技术对自动流量平衡阀过流端帽工作面进行强化以增加其使用寿命。详细分析了不同激光参数如脉冲电流、扫描速度、脉冲频率和离焦量等因素对过流端帽表面硬化的影响。实验结果表明:只要工艺参数选择适当,可获得很好的表面硬化质量,且能提高生产效率。Over-current end cap of automatic flow control valves was strengthened by using laser surface strengthening technology in order to increase its service life. The influences of the different laser parameters to surface strengthening, such as laser pulse current, scanning speed, pulse frequency and defocus, were analyzed. Experimental results show that as long as the appropriate laser parameters be chosen, good surface hardening quality can be obtained, and the production efficiency can be improved.
