【摘要】 研究了Ｆｅ＿３Ａｌ基合金在ＰｅＣｌ３溶液及天然海水中的腐蚀性能，结果表明，在ＦｅＣｌ３溶液中合金元素能较大地提高Ｆｅ３Ａｌ的耐蚀性，而稀土Ｃｅ则对Ｆｅ３Ａｌ的耐点蚀性有显著的影响；与其它状态相比，经氧化处理表面的ＦｅＡｌ基合金耐用蚀性能最佳，海水短期腐蚀试验显示Ｆｅ３Ａｌ基合金与３１６Ｌ不锈钢的耐蚀性大致相同。更多还原

【Abstract】 Corrosion resistance of Fe3Al-based alloys is studied in FeCl3 sloution and natural seawa-ter.The results show that the corrosion resistance of Fe3Al-based alloys is improved greatly by additionof Cr in the FeCl3 solution,and the pitting corrosion resistance is improved significantly when Ce isadded.The corrosion resistance of Fe3Al-based alloys becomes much higher if specimen oxide film treat-ment is used.A short-term test in seawater indicates that the corrosion resistance of Fe3Al-based alloyscan match with the 31 6L stainless steel.更多还原
