【摘要】：開發(fā)的深層滲氮硬化技術(shù)可以提高滲氮件的承載能力和挖掘滲氮的強(qiáng)化潛力。它包含三個(gè)相關(guān)條件:滲氮層深0.6 mm以上,滲氮表面下0.4 mm處硬度大于600 HV和滲氮基體硬度大于400~450 HV(42~46 HRC)。研制的兩種時(shí)效硬化鋼(20Cr Ni3Mn2Al和20Cr3Mn Mo V)空冷固溶處理后硬度分別為33~36 HRC和40~44 HRC;經(jīng)過(guò)520~540℃×50 h深層離子滲氮處理后,滲氮層深分別為0.75 mm和0.60 mm,滲氮表面下0.4 mm處硬度分別達(dá)到652 HV0.1和748 HV0.1,滲氮基體硬度分別為431 HV0.1(44.5 HRC)和488 HV0.1(48.5 HRC)。
[Abstract]:The deep nitriding hardening technology developed can improve the bearing capacity of nitriding parts and excavate the potentiality of nitriding. It contains three related conditions: the depth of nitriding layer is more than 0.6 mm, The hardness is greater than 600HV at 0.4 mm below the nitriding surface and the hardness of the nitriding matrix is more than 400,450 HV(42~46. The hardness of the two aging hardening steels, 20Cr Ni3Mn2Al and 20Cr3MnMo V, are 33 ~ 36 HRC and 4044 HRC respectively after being treated by deep ion nitriding at 540 鈩，
