摘要
应用动电位扫描法和电化学阻抗法研究了钨酸盐和苯并三唑(BTA)在氯化钠介质中对X70钢的协同缓蚀作用。结果表明:X70钢在0.03%的NaCl溶液中的腐蚀为混合控制过程。Na2WO4.2H2O和苯并三唑均为阳极型缓蚀剂。在保持缓蚀剂总浓度为2×10-3mol/L时,Na2WO4.2HO∶BTA为1∶1时缓蚀率达最大,为83.01%。
The corrosion inhibition behaviors of tungstate or/and benzotriazole（BTA） in 0.03% NaCI solution were studied using polarization curves and electrochemical impedance spectroscopy（EIS）. The inhibition efficiency of tungstate was higher than that of BTA. With the concentration ratio of tungstate/BTA being 1 ： 1 at the total concentration of 2 × 10^-3 mol/L, the inhibition efficiency reached the max 83.01%.
