Abstract

Abstract

The sulfidation kinetics of Fe25Cr20Ni were cairied out at H₂S-H₂ atmospheres by means of continuously-weighing device and non-continuously weighing device. Sulfidation kinetics curves of the alloy obeys parabolic law.The composition and morphology of sulfide scales were also studied. All sulfide scales consist of two surface layers in addition to subscale. Two surface layers are controlled by predominant diffusion of metals. The subscale growth is controlled by the inward diffusion of suffur.
