The corrosion mechanisms are characterized by the linear polarization and the electrochemical impedance spectroscopy measurements, and the corrosion products are analyzed by the laser Raman spectrometry. It is shown that the Fe-Cr alloy is attributed for the passive film, which is formed more easily when the alloy contains a large quantity of Cr element. In the early immersion, the corrosion rate of Fe-Cr alloy is very small. With the immersion time increases, the passive current density firstly increases, and then decreases. The passive film can well prevent the Cl^- and SO₄^2- anion erosions. For Fe-Cr alloy, pitting occurs in an acidic solution, and it increases its extent with the increase of the immersion time. If the Fe-Cr alloy is immersed in the solutions for 150 h, the corrosion products appear in the near grain boundary, and are more likely to occur in the triangle grain boundary. The corrosion products of the Fe-Cr alloy contain CrOOH., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=Z3rJSv8UMSmQrIYQOox7Yw==, pdfFileSize=3147849, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, authorCompany=1.
