Abstract: The inhibition behavior of triethanolamine for magnetic refrigeration material LaFe11.0Co0.7Si1.3 in distilled water at room temperature has been investigated. Potentiodynamic polarization curves were applied to study the alloy corrosion behavior in the absence or presence of different concentrations of inhibitor. Results revealed that the inhibition efficiency increased with increasing the inhibitor concentration and the inhibitor worked as anodic inhibitor. The solution with 20 mL/L triethanolamine has the best inhibition efficiency reaching the values of inhibition efficiency (ε%) up to 69.9%. Corrosion inhibition mechanisms for inhibitors were proposed in this work.
