摘要：
The effects of 5 wt.-% Al and 10 wt.-% Al on the sulfidation behaviour of the Fe-25Cralloy in H2S-H2gas mixtures in the temperature range of 700～900 C has been studied.Thesulfidation resistance of Fe-25Cr was improved and the sulfide scale morphologies,compositionand structure of Fe-25Cr changed remarkably.The sulfidation kinetics of the alloys with alu-minium obeyed basically the parabolic law after an initial period of reaction time.The sulfida-tion mechanism of the Fe-Cr-Al alloy has been proposed.
