用恒电流极化测定方法研究了一些取代的苯基-N苯氨基甲酸酯对铁在2NHCl溶液中的缓蚀作用。用不同浓度的缓蚀剂进行研究表明这些化合物是作为混合型缓蚀剂起缓蚀作用的,研究结果表明添加剂(缓蚀剂)通过苯氧基中的氧原子和NH基中N原子的吸附作用降低腐蚀率,这些化合物的缓蚀性能取决于浓度和它的化学组成。用电化学测定验证了电毛细测定的结果它们是一致的,计算监讨论了缓蚀剂吸附作用的热力学参数。
The corrosion inhibition of some substituted phenyl-N-phenyl carbamates on iron in 2N HCl solution was studied by the galvanostatic polarization assay. Studies with different concentrations of corrosion inhibitors show that these compounds act as a corrosion inhibitor for the mixed type. The results show that the additives (corrosion inhibitors) pass through the oxygen atoms in the phenoxy group and the N atoms in the NH group The role of reducing corrosion rate, the corrosion inhibition of these compounds depends on the concentration and its chemical composition. The results of electrocapillary measurements were verified by electrochemical measurements to be consistent, and the thermodynamic parameters for corrosion inhibitor adsorption were calculated.
