Abstract The effect of external direct current electric field on the inhibition behavior of cyclohexylamine and sodium nitrite under simulated atmospheric environments with thin electrolyte layers was investigated by surface characterizations and electrochemical measurements. Results confirmed that the vertical electric field from top to bottom increased the inhibition efficiency of cyclohexylamine but decreased that of sodium nitrite. The opposite electric field weakened the inhibition efficiency of cyclohexylamine but enhanced that of sodium nitrite. Surface analysis indicated that the external vertical electric field can affect the migration of inhibitors under thin electrolyte layers.

外直流电场对薄电解质层下环己胺和亚硝酸钠抑制行为的影响

摘要 通过表面表征和电化学测量研究了外部直流电场对具有薄电解质层的模拟大气环境下环己胺和亚硝酸钠抑制行为的影响。结果证实，自上而下的垂直电场增加了环己胺的抑制效率，但降低了亚硝酸钠的抑制效率。相反的电场减弱了环己胺的抑制效率，但增强了亚硝酸钠的抑制效率。表面分析表明，外部垂直电场会影响薄电解质层下抑制剂的迁移。
