The effects of 5 wt.-% Al and 10 wt.-% Al on the sulfidation behaviour of the Fe-25Cralloy in H2S-H2 gas mixtures in the temperature range of 700～900 C has been *** resistance of Fe-25Cr was improved and the sulfide scale morphologies,compositionand structure of Fe-25Cr changed *** sulfidation kinetics of the alloys with alu-minium obeyed basically the parabolic law after an initial period of reaction *** sulfida-tion mechanism of the Fe-Cr-Al alloy has been proposed.

Iron suffered low temperature hot corrosion (LTHC) in the presence of salt deposits of Na2SO4,Na2SO4 mixed with NaCl and Na2SO4 mixed with V2O5 in a combustion gas at 600℃. The additions of NaCl to Na2SO4 and of V2O5 to Na2SO4 changed the corrosion kinetics significantly and modified the scale structure markedly It is proposed that trivalent iron ions were more favored than divalent ions in the eutectic responsible for the occurrence of LTHC when NaCl was present, while the reaction between Na2SO4 mixed with V2O5 and the gas formed (Na2O)xV2O4(V2O5)6-x providing directly the liquid required by LTHC. The suphide formation in the inner FeO larer was related to the sites of the reduction step wher SO2 was released.

The sulfidation rate constants of various Fe-Mo binary alloys in S2 vapor with different sulfidation parameters were collected to summarize the correlation between the sulfidation rate and alloy composition, sulfur pressure and sulfldation temperature. The octivation energies indicate that the sulfidation process of the alloys is exclusively controlled, at a given temperature, by one alloying component i.e. either Mo or Fe. The sulfidation rate declines exponentially with the increasing of Mo content in alloy. And the influence of sulfur pressure is relatively slight.

通过金属蒸汽真空弧离子源（简称ＭＥＶＶＡ）方法在Ｆｅ３Ａｌ表面离子注入Ｙ。在１０００℃空气中的氧化实验表明，Ｆｅ３Ａｌ经离子注入Ｙ后，初期氧化速率略有升高，但稳态氧化速率大大降低，氧化膜的塑性和粘附性大大提高，抗氧化性能明显改善。其原因在于注入的Ｙ＋在氧化过程中优先氧化，阻碍金属离子向外扩散，促进氧向内传输，改变了氧化膜的形成和生长机制。
