Potential transmission and transients during corrosion: Applications to corrosion monitoring

The transmission of potential along a passive metal/electrolyte interface, which is important in corrosion monitoring, has been considered for transitory and sustained corrosion processes. The observed signals are modified and delayed by the passive surface. Analysis, based on a transmission line as the equivalent circuit of a pipe and the impedance characteristics of the passive-metal-solution interface, allows the effectiveness of corrosion monitoring methods to be considered.
