摘要
用电化学方法研究了(3-(4-氯苯基异恶唑-5-基)甲醇(CPIM)和(3-(2,4二氯苯基异恶唑-5-基)甲醇(DCPIM)在1 M HCl中对低碳钢的缓蚀效果，温度分别为40℃和50℃。极化研究表明，缓蚀剂为高效混合型缓蚀剂，缓蚀剂的缓蚀性能随缓蚀剂浓度的升高和温度的降低而提高。通过适当的等效电路模型对EIS测量结果进行分析，以模拟腐蚀抑制作用。
Corrosion inhibition of mild steel surface by isoxazoles in HCl solution: Electrochemical studies
The corrosion inhibition efficiency of (3-(4-chlorophenyl isoxazole-5-yl) methanol (CPIM) and (3-(2,4 dichlorophenolisoxazole-5-yl) methanol (DCPIM) for mild steel in 1 M HCl has been studied using electrochemical methods at 40 and 50 °C. Polarization studies showed that the inhibitors are efficient mixed-type corrosion inhibitors, and their inhibition performance increased with the rise of inhibitor concentration and decrease of temperature. The result of EIS measurements was analyzed through an appropriate equivalent circuit model to model the corrosion inhibition.
