| Abstract: | The processes of low temperature ionitriding and gas nitrocarburizing for spiral springs have been studied. The spiral springs were made of 50CrVA steel wire and were heated by electric contact and quenched continuously passing the oil,thereafter they were tempered at same production Iine. The structures of nitriding layer and fatigue property of them were observed and analysed. The results were proved that fatigue life of the springs have been raised. Finally the shearing fatigue model of the surface strengthening spring is suggested. |
