Study on Seawater Corrosion of Fe-Al Intermetallic Compound

Abstract:

Article Preview

The corrosion behavior of Fe3Al intermetallic compounds annealed at various temperatures in sea water was studied. The results indicated that both structure ordering and surface oxidation film can significantly improve the anti-corrosion performance of Fe3Al alloys. Furthermore, there was no significant difference in anti-corrosion performance between Fe3Al samples of DO3 and B2 structure. The corrosion mechanism of Fe3Al alloys in seawater was probably as follows: Al element is preferentially corroded, Fe corrosion followed when Al element has been corroded away from the sample surface as well as the reduce ratio of Al becomes smaller than the dissolution ratio of Fe.
