Abstract
Austenitic Fe-Cr-Ni alloys that contain 2–4%Si are highly resistant to intergranular corrosion in highly oxidizing HNO 3 solutions; however, alloys that contain only 0.5–1%Si corrode rapidly in these environments. The mechanism by which Si additions affect corrosion behaviour has been studied by corrosion testing, electrochemical polarization, electron microscopy, and electron diffraction techniques. Results of these studies indicate that the corrosion resistance is related to the formation of a Si-rich passive oxide film.
