A Study of the Mechanism of Corrosion of Some Ferritic Steels in High- Pressure Carbon Dioxide with the Aid of Oxygen-18 as a Tracer II. High- Silicon Mild Steel
The oxidation mechanisms of a high-silicon mild steel (a fully killed steel) in high pressure (4.1 MPa) CO_2 at 773 K have been investigated with the aid of 18O as a tracer. In the protective region of oxidation oxide formation occurred at the oxide-gas interface, within the scale and possibly also at the oxide-metal interface. The oxide growth within the scale is believed to occur in a relatively stress-free manner. The results for this steel are compared with those for a low-silicon mild steel, Fe-9% Cr alloys, and nickel.
