摘要:The oxidation of stainless steel with Fe-Sn intermetallics adhesion in 300 degrees C water was studied by analyzing the morphologies and phase structures of surface oxide films. The oxidation behavior of stainless steel was discussed in order to illustrate the effect of Fe-Sn intermetallics on the oxidation characteristic. Larger size of faceted spinel and small size of SnO2 particles are observed on the samples with Fe-Sn intermetallics adhesion, whereas smaller faceted hematite and spinel grow on the samples without Fe-Sn intermetallics adherence. The surface intermetallics aggravates the spalling of oxide particles and decreases the corrosion resistance of stainless steel. Such deterioration is attributed to the loose microstructure characteristic and the poor corrosion resistance of SnO2 particles formed in high temperature water.
