摘　　要：在含氯化钠和盐酸的流动介质中研究铁的腐蚀行为以及苯并三唑和六亚甲基四胺对阳、阴极过程的影响。这两种含氮有机物均对铁上的析氢反应产生强烈的阻化作用,归因于阻塞效应和静电效应。发现有机物浓度的对数与缓蚀效率的对数成线性关性,它们的吸附遵循修正的Freundlich等温线。The corrosion behuviour of iron in flowing acidie NuCl solution as well as the inflluences of benzotrriazole and hexamethylene-tetramine on anodic and cathodic proccsscs were inveshgated. These nitrogen-containg compounds were found to strongly inhibit the hydrogen evolution reaction on iron, attributing to both block effect and clectrostatic effect. From the variation of inhinition effeciccy η with the inhibitor concentration C, it was concluded that the plot of log η against log C is linear and that the adsorptions the compounds follow empirical Freundlich isotherms.
