Methods of enhancing the corrosion resistance of an oxidizable material exposed to a supercritical fluid is disclosed One method includes placing a surface layer on an oxidizable material, and choosing a buffered supercritical fluid containing a reducing agent with the composition of the buffered supercritical fluid containing the reducing agent chosen to avoid the corrosion of the surface layer or reduce the rate of corrosion of the surface layer and avoid the corrosion of the oxidizable material or reduce the rate of corrosion of the oxidizable material at a temperature above the supercritical temperature and supercritical pressure of the supercritical fluid. |
