The corrosion behavior of LaFe11.6Si1.4 alloy was investigated in benzotriazole and sodium benzoate mixed solution. Polarization measurements and electrochemical impendence spectroscopy techniques were used to measure the electrochemical parameters. Experiment results show that the inhibition efficiency is influenced strongly by the concentration of benzotriazole and pH value. The high concentration benzotriazole and high pH value are beneficial to form a compact oxidation layer and thus prevent the dissolution of Fe.
