| Abstract: | The effects of the nitriding temperature and time on the microstructure and the wear resistance property of the nitride layers were investigated by the ionic nitriding process on 4Cr2MoWVNi steel. The results showed that the optimal nitriding depth and surface micro hardness were gained with an appropriate treating temperature and time. The hot wear resistance was enhanced remarkably with a certain nitrided layer, the service life of the die was prolonged greatly. |
