研究LaFe11.6Si1.4合金在苯甲酸钠与苯并三氮唑混合溶液中的腐蚀行为.利用动电位极化曲线与电化学阻抗谱对合金的耐腐蚀性进行表征.结果显示,高浓度的苯并三氮唑和高pH值有利于形成厚的氧化层,进而降低合金表面Fe的溶解.

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.
