✦ Synopsis

environments was investigated. The corrosion rate is higher under 'outlet' conditions at 700°C compared to standard conditions at 650°C and 'inlet' conditions at 600°C. The corrosion potential increases with time when a protective corrosion layer is formed. Eventually it reaches a more positive potential, close to the cathode operating potential. On Thermax 4762 steel, the corrosion layer grows relatively quickly in the first 48 h, then slows down when a protective layer is formed. The corrosion layer consists of an Fe-rich outer layer and a protective AI-and Cr-rich inner layer.
