| Abstract: | The fatigue wear mechanism on electro-discharge machining surface of coId stamping die made ofCrWMn steel has been analysed. The wear resistance of electro-discharge machining surface of Cr12 steel with animpact load has been studied' The results show that the fatigue wear,on electro-discharge machining surface,wasrelated with the carbide network in steel. The tempered layer with a lower hardness can speed up the fatigue wearof dies. The wear resistance of electro-discharge machining surface of Cr12 steel is higher |
