ABSTRACT

ABSTRACT: In this paper, corrosion behavior of stainless steel 316 was studied in low oxygen concentration supercritical water containing 0.1% H2O2 using weight measurement, scanning electron microscopy, and X-ray diffractometry. It was found that the mass gain increased linearly with exposure time in 0.1% H2O2 supercritical water. At the low oxygen concentration, there were non-continuous oxide powders which mainly contained Fe and O forming on the surface of stainless steel 316. Fe oxide consisted of Fe2O3 and Fe3O4.
