【摘要】：采用等離子體滲氮技術對鑄鐵材料進行氮化處理,研究了滲氮前后鑄鐵的組織和性能變化。結(jié)果表明,當滲氮溫度不變,保溫時間為10~12 h時,滲層深度和顯微硬度隨著保溫時間的延長而增大。保溫時間不變,滲氮溫度為560~600℃時,滲層深度和顯微硬度隨溫度升高先增大后減小。在580℃滲氮時,鑄鐵的組織主要為γ′相和ε相,硬度值達到最大值。
[Abstract]:The microstructure and properties of cast iron before and after nitriding were studied by plasma nitriding technology. The results show that when the nitriding temperature is unchanged and the holding time is 10 脳 12 h, the depth and microhardness of the nitriding layer increase with the prolongation of the holding time. When the nitriding temperature is 660 鈮，
