论文名称：Early oxidation of Super304H stainless steel and its scales stability in supercritical water environments

发表刊物：International Journal of Hydrogen Energy

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.
