- 摘要：
- The early oxidation of Super304H stainless steel exposed to supercritical water at 450 C,
540 C, and 580 C was characterized. After a 40 h exposure, distribution density of oxide
grains produced on samples increased with experimental pressures, while initial aqueous
pH had a negligible influence on short-term corrosion morphologies, implying that the
outer oxide layer of scales may form via solid growth mechanism rather than by metals
dissociation/oxides precipitation process. After a repeated 24 h cycles of exposure at
condition of 540 C/25 MPa followed by that of 500 C/23 MPa up to 5 cycles, partial spallation
of the scales appeared along inner and outer layer interface, not substrate/scales
interface due to the enhanced adhesion of scales on the substrate by pinning effects and
production and convergence of cavities at the inner/outer layer interface.
