【Abstract】 The H13 mould st e el was nitrided in a 10kW plasma nitridi ng furnace.Effects of the nitriding temp erature and time on microstructure and p roperties of the nitride layers were inv estigated.The results show that the opti mal phase composition and surface microh ardness were gained with a appropriate n itriding temperature and time.The wear r esistance were enhanced remarkably with a certain nitriding depth.更多还原
