Electrochemical Corrosion Behavior of Iron Aluminides in Sulfuric Acid
Abstract
<jats:p>In the present work, samples of a binary intermetallic alloy (Fe<jats:sub>3</jats:sub>Al) with 26at.%Al were submitted to electrochemical corrosion evaluation in a 0.5M H<jats:sub>2</jats:sub>SO<jats:sub>4</jats:sub> solution containing naturally dissolved oxygen. The corrosion resistance was evaluated by applying linear polarization, electrochemical impedance spectroscopy and potentiodynamic polarization at 22 and 35°C. The results obtained revealed that in both conditions the material exhibits active-passive behavior. Heating to 35°C did not alter the passivity characteristics of the alloy (passivation range and passive current density), but elevated the corrosion current density and the critical current density. The polarization resistance of the samples was also decreased with temperature, following the trend observed for the corrosion current density.</jats:p>
