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.
