CORROSION-BEHAVIOR ANALYSIS OF A Fe-Al LAYER IN SEAWATER CHARACTERIZED BY STATIC CHEMICAL ETCHING
Keyword(s):
The static corrosion behavior of a Fe-Al layer was investigated with an immersion test in seawater, using XRD and SEM with EDS, testing the corrosion rate. The results showed that phases -Al2O3, Fe2O3 and MgO were the main corrosion products on the Fe-Al layer surface, while corrosion pits and holes were also observed. It was found that the Fe-Al layer fabricated at 750 °C exhibits a better corrosion resistance, having smaller corrosion pits and holes and also a low corrosion rate. This was related to a good formation ability of the alumina passive film.
