Scaling Properties of Galvanic Current Measured by Atmospheric Corrosion Monitors

摘要

The galvanic currents of Atmospheric Corrosion Monitors exposed to the atmosphere are analyzed in order to investigate the scaling behaviors of corrosion. It is found that the time series of the galvanic current have the scaling properties and a scaling relation derived from the scaling theory is consistent with the experimental results. The Hurst coefficient representing the effect of long memory is related to the type of corrosion.
