摘要
合成了一种新型缓蚀剂——50%K2O-25%CaO-25%P2O5的玻璃,并用电化学阻抗谱法(EIS)研究了其在1 M HCl摩尔盐酸中的缓蚀作用。对EIS测量数据进行分析,通过适当的等效电路模型对缓蚀过程进行建模。实验结果表明,磷酸盐玻璃是一种高效的缓蚀剂,缓蚀率随缓蚀剂浓度的增加而增加,在500 ppm时可达93%。详细讨论了所研究玻璃体系的缓蚀机理。
Inhibiting corrosion effect of Phosphate glass on mild steel in acid solution
A new corrosion inhibitor, namely glass of composition 50%K2O-25%CaO-25%P2O5 has been synthesized and its inhibiting action on the corrosion of mild steel in molar hydrochloric acid (1 M HCl) has been investigated using electrochemical impedance spectroscopy method (EIS). Data obtained from EIS measurements were analyzed to model the corrosion inhibition process through appropriate equivalent circuit model. The experimental results revealed that Phosphate glass is an efficient inhibitor and the inhibition efficiency increases with increase in inhibitor concentration, reaching value up to 93% at a concentration of 500 ppm. The inhibition mechanism of the studied glass system was discussed in details.
