摘要:本文采用失重法,电化学交流阻抗法,极化曲线法和扫描电镜法等观察缓蚀剂在HCl介质中,FCI-3及普通碳氢表面活性剂(CTAB、SDS、TX-100)复配体系对Q235钢的缓蚀性能。结果表明,FCI-3对碳钢表面有较好的缓蚀性能,三种方法测试的结果均达到90%以上;三种普通碳氢表面活性剂分别与FCI-3复配后,发现三个体系仍有较好的缓蚀效果,缓蚀效率达到90%以上,缓蚀效率从高到低的顺序是CTAB>TX-100>SDS。

AbstractThe corrosion inhibition properties of fluorocarbon surfactant FCI-3 and the mixed systems of FCI-3 and other hydrocarbon surfactants (CTAB, SDS, TX-100) were studied by weight loss method, electrochemical impedance spectroscopy,polarization curves methodand scanning electron microscopy. The results indicated that the inhibition performance of FCI-3 for carbon steel was good,and the inhibition efficiency reached above 90% by three methods mentioned above. The inhibition performances of the mixed systems for FCI-3 and hydrocarbon surfactants were also excellent and reached more than 90%. The order of inhibition efficiency from high to low is CTAB>TX-100>SDS.
