結(jié)果真空滲碳為真空滲碳一淬火工藝曲線。在真空中加熱到滲碳溫度并保溫使表面凈化、活化之后，通入稀薄滲碳富化氣(見控制氣氛熱處理)，在大約1330Pa(10T0rr)負(fù)壓下進(jìn)行滲入，然后停氣(降壓)進(jìn)行擴(kuò)散。滲碳后的精密鋼管淬火采用一次淬火法，即先停電，通氮冷卻工件至臨界點(diǎn)A，、以下，使內(nèi)部發(fā)生相變，再停氣、開泵，升溫到Ac1，～Accm之間。淬冷方法可采用氣冷或油冷。后者為奧氏體化后移入前室，充氮至常壓，入油。真空滲碳的溫度一般高于普通氣體滲碳，常采用920～1040℃滲入和擴(kuò)散可按所示分兩階段，也可用脈沖式通氣、停氣，多段式的滲一擴(kuò)相間，效果更好。由于溫度高，尤其表面潔凈、有活性，真空滲碳層形成速度比普通氣體、液體和固體滲碳快，如要求滲層為1mm時(shí)，在927℃只需5h，而1033℃僅需1h。
