“…The formation of carbide phases (Fe 3 AlC 0.69 ) by addition of carbon to the FeAl intermetallic base, promotes selective dissolution of microstructure, reaching more positive potentials, however, the corrosion resistance and passive layer formation diminishes with the carbon addition increasing (7). In this sense, the passivity and breakage of films formed on Fe 3 Al-Cr-Mo base alloys in thiosulfate solutions with chloride was realized (8), this study showed that anodic current density decreases as polarization potential increases due the Mo addition. The increase in the potential of both corrosion and pitting, and the difference between those, shown that the increase in corrosion resistance is due to the effect of Clcontent.…”

The corrosion study of Fe-40Al+2% Rare Earths (RE) intermetallic alloy in NS4 solution at room temperature was carried out. The intermetallic alloy was previously produced by melting in an induction furnace. The alloy microstructure is constituted by a minority phase of Fe3Al, homogeneously dispersed in the majority phase of FeAl. The effect of pH condition was presented in the corrosion mode, at pH 5 the sample showed uniform corrosion, while at pH 3 and 7 some pitting sites were observed, however the metallic samples showed uniform corrosion on the exposed areas. The anodic dissolution mechanism occurred preferentially in the FeAl phase observed at pH 3, which corresponds to the majority phase or alloy microstructure. Electrochemical results were complemented with the microstructure and chemical characterization by scanning electron microscopy, energy dispersion spectroscopy and X-ray diffraction analysis.
