【摘要】：研究Fe-Zn化合物粘附的304不銹鋼在高溫高壓水中的腐蝕行為,采用掃描電子顯微鏡(SEM),X射線衍射分析儀(XRD)和同步輻射率入射衍射(SR-GIXRD)評價(jià)生長氧化物的顯微結(jié)構(gòu),討論Fe-Zn化合物粘附對不銹鋼基體腐蝕性能的影響。結(jié)果表明,不銹鋼在300℃水中腐蝕后,表面生長細(xì)小Fe_2O_3氧化物和外層塊狀或片狀的Fe_3O_4氧化物。Fe-Zn化合物粘附的不銹鋼經(jīng)過高溫高壓水腐蝕后,Fe-Zn化合物主要轉(zhuǎn)變成ZnO,隨著腐蝕時(shí)間的增加,腐蝕產(chǎn)物ZnO逐漸脫落,樣品的失重量不斷增加;腐蝕時(shí)間增加到360和480 h,不銹鋼表面較細(xì)小的Fe_2O_3氧化物顆粒顯露,樣品的失重量變化不大。通過SR-GIXRD能夠表征較薄的Fe_2O_3氧化膜,而普通XRD不能準(zhǔn)確表征。
[Abstract]:The corrosion behavior of 304 stainless steel adherent to Fe-Zn compounds in high temperature and high pressure water was studied. The microstructure of grown oxides was evaluated by scanning electron microscopy (SEM) and synchrotron radiance incidence diffraction (SR-GIXRD).The effect of adhesion of Fe-Zn compounds on corrosion resistance of stainless steel substrate was discussed.The results show that the stainless steel is corroded in water at 300 鈩，
