Abstract

The corrosion behavior of the ferritic oxide dispersion strengthened (ODS) steel (14Cr-3Al-2W-0.1Ti) prepared by adding YH₂ nanoparticles (NPs) was investigated in supercritical water (SCW) at 600 °C for 1500 h. The mass gain of the ODS steel (215.5 mg/dm²) was lower than that of SUS430 steel (357.2 mg/dm²). A dual oxide layer generated on the surface of ODS steel after corrosion in SCW. The outer layer was composed of Fe₂O₃ and Fe₃O₄, while the inner layer composed of the spinel-type FeCr₂O₄ together with Al₂O₃. The generation of Y₂Ti₂O₇ NPs in the ODS steel by adding YH₂ NPs prohibits the formation of Y-Al-O particles and leaves more Al available to form a continuous protective oxide scale to improve the corrosion resistance. Moreover, the Y₂Ti₂O₇ NPs act as efficient barriers to suppress the outward diffusion of metal atoms. This novel ODS steel shows potential applications in supercritical water.
