摘　　要：对动车组制动系统国产化部件中要求做表面高频淬火的一种螺栓进行了工艺试验研究,通过大量的试验,对工艺参数进行优化后,最终生产出了满足图纸中表面淬火技术要求的零件。In the braking system of EMU,there is a kind of bolt which requires high frequency quenching process.In this paper,the process is studied by lots of test,the process parameters are optimized,and eventually the bolt that can satisfy the drawing requirement of surface hardening technology is produced.

关 键 词：高频淬火 硬度 螺栓
