摘　　要：本文研究饱和海水湿气环境中对 90 7A钢施加缓蚀剂的防蚀作用 ,利用恒电量技术等电化学方法对同材质的三电极大气腐蚀监测探头 (ACM )进行腐蚀测量 .结果表明 :利用电化学方法监测薄层缓蚀剂液膜的防蚀效果可以更清楚地获知缓蚀剂成膜的过程 。The corrosion inhibiting behavior of 907A steel,which was covered with thin inhibitor layers in moist seawater atmosphere,was studied.The electrochemical measurements,including EIS method and the coulostatic method,were used to atmospheric corrosioed monitor(ACM)under thin inhibitor layers to determine its corrosion rate.The results shown that the application of electrochemical methods such as the coulostatic technique and EIS could readily detect the on going process of film formation. Hence, the rapid evaluation of the thin inhibitor layers for 907A steel might be possible.
