摘要：

The electrochemical behavior of Fe-40at.%Al-based intermetallic microalloyed with 3 and 5 at.% Cu additions in 0.25 M H2SO4 solution over time was studied. A complementary study to characterize the surface morphology and semiquantitative chemical analysis of the corrosion products after 24 h of immersion was performed using scanning electron microscopy and x-ray energy dispersion spectrum. By means of electrochemical techniques, it was shown that Cu addition has a positive effect on corrosion resistance of Fe-40at.%Al-based intermetallic alloy. Additionally, the relatively high concentration of Cu consolidated the passive film of corrosion products and its stability.
