Corrosion Behavior Research of Fe₃Al Intermetallic Compound in H₂S/CO₂ Environment

Abstract:

The corrosion behavior of Fe₃Al was studied by high temperature autoclaves in H₂S/CO₂ environment. By Stereo Microscope, we found that the corrosion film of Fe₃Al is thin and crack at 60°C, 4.0 Mpa,after 72h in autoclaves; Phase analysis by XRD showed that the main composition of corroded products is FeS; its corrosion are Ⅲ corrosion resistant type and corrosion rating of 4, mainly pitting, and average corrosion rate of 0.2106 mm/a.
