摘要: Abstract The corrosion behavior of ferritic–marensitic steel P92 with and without Ar-ions irradiation in supercritical water at 823 K(550 °C)/25 MPa for different exposure times was investigated by a variety characterization techniques. A distinct difference oxidation morphology between irradiated unirradiated samples observed. oxide relatively moderate radiation intensity similar that irradiation. Many small particles were observed the region high but their size increased gradually increasing times. Exfoliation layer occurred exposed 100 h. Chromium-rich chromium content more than 20 wt pct along small-scale three-layer structures samples, arising from microstructural change after Mechanism exfoliation is also discussed.
