摘要: 采用自制的固体三电极体系，将恒电量仪与微计算机联机进行在线测量，测得了４５钢、１８－８不锈钢和Ｈ６２黄铜在几种气相缓蚀剂中的Ｒｐ、Ｃｄ、Ｒｆ和Ｃｆ值，进而评价了它们的缓蚀效率，并把测定结果与失重法进行了比较。

关键词 ：恒电量方法, 气相缓蚀剂, 固体参比电极

Abstract：A solid state reference electrode was designed tO study metal corrosion in the presence of vapour phase inhibitors. A home-made three electrode system was used in combination with a coulostatic perturbation mater and a micro-computer as on-line measurement system. The inhibition performance of several vapour phase inhibitors for carbon steel(0.45%C), 18-8 stainless steel and H62 brass was examined. Based on the analysis of E-T sttenustion curves, relevant parameters Rp, Cd, Rf and Cf in equivalent circuit for the electrode system were obtained, thus the inhibitors could be enduated quicldy. The results from the coulostatic method were consistent with those from weight-loss testing.

Key words： Coulostatic method Vapour phase inhibitor Solid state reference electrode
