摘要	Abstract Effects of Y2O3 on the oxidation behavior of 304 SS with coating by laser remelting after exposed to 290 °C water containing 3 ppm O2 for 72 h were investigated. It was found that the corrosion behavior of remelted layer on 304 SS with the addition of Y2O3 was completely different from that of 304 SS and remelted layer on 304 SS without the addition of Y2O3. More Cr2O3 hematite oxides were formed around strengthening phase near the Y2O3 particles. With increasing exposure time, a little number of Fe3O4 spinel oxides were continuing formed on the surface outside the Mn/Si enrichment area. The growth of Fe3O4 spinel oxides were hindered because of the massive Cr2O3 hematite oxides around the Y2O3 particles. Some small Fe3O4 spinel oxides were formed. Finally, the types of oxide film formed on the surface of the remelted layer with the addition of Y2O3 were mainly Cr2O3 hematite oxides and a few of fine FeCr2O4 spinel oxides. The addition of Y2O3 in laser remelting layer can obviously change the corrosion behavior of 304 SS exposed to high temperature water and the related mechanisms are also discussed.
