A Novel Corrosion Rate Monitoring Method for Steel in Neutral Aqueous Solution Based on Tafel Extrapolation Method

It is important to monitor the corrosion rates of steel in electrolyte environments such as aqueous solution or soil in order to evaluate the integrity of the members of facilities. As the nondestructive monitoring method polarization resistance (Rp) method is generally known. The corrosion rate icor is calculated by the equation of icor=k/Rp . Herein k is a constant decided on the specific condition of steel surface and the environment. It is not easy to decide k on each condition. As a monitoring method without deciding k has been demanded CIPE (Current Interrupted Polarizing Extrapolation) method was developed. By CIPE method the corrosion rate is calculated by the Tafel equation obtained from the polarization curve of the in situ measurement. In this paper in order to confirm accuracy of the method the measured corrosion rates were compared with the values calculated from mass losses of steel specimens in neutral aqueous solution. As a result the actual corrosion mass losses gave good agreement with the values of coulomb amounts which were calculated from the corrosion rates monitored by CIPE. Therefore it is clear that CIPE is a useful method for real time monitoring of corrosion rate of steel in aqueous solution.
