Corrosion Resistance of Fe3Al Based Alloys to Simulated Exhaust Gas

Materials Science and Engineering School, UST Beijing, Beijing 100083, Chin

摘要: 研究了Fe-28Al-5Cr,Fe-28Al-5Cr-0.5Nb-0.1C合金及其采用鎢極氬弧焊焊接的Fe₃Al基合金焊縫,在模擬汽車尾氣氣氛中的腐蝕行為,分析了腐蝕產物的組成及形成機理,并與目前在汽車尾氣系統應用的A3低碳鋼及1Cr18Ni9不銹鋼進行對比,結果表明,由于在實驗條件下Fe₃Al基合金及其焊縫表面形成了一層致密的Al₂O₃氧化膜,與不銹鋼相同,顯示出優良的抗蝕性能.與此相對比,由于A3鋼表面形成疏松的Fe₂O₃膜容易剝落,而使腐蝕加劇.

Abstract: The behavior of corrosion resistance to simulated exhaust gas of Fe-28Al-5Cr, Fe-28Al-5Cr-0.5Nb-0.1C and GTA (gas tungsten arc) welded Fe₃Al based alloys has been investigated. The composition and emerging mechanism of corrosion scale have been analyzed, and compared with former materials used in the exhaust manifold system such as low carbon steel A3 and 1Cr18Ni9 stainless. The results indicates that Fe₃Al based alloys and its weldment exhibited corrosion resistance to the test environment as good as stainless because of the producing of continuous and dense Al₂O₃ surface scale, by contrast, the oxide of A3 steel was loose and discontinuous Fe₂O₃ scale which was easy to be peeled off and led corrosion accelerated.
