4 - Electrochemical polarization technique based on the nonlinear region weak polarization curve fitting analysis

Abstract

The chapter introduces an electrochemical polarization technique based on the nonlinear region weak polarization curve fitting analysis. Firstly, the author shows the various transforms of the Butler-Volmer equation at different mass transfer or electrochemical polarization conditions for corrosion monitoring. Secondly, numerical simulation of the polarization curves based on the Butler-Volmer Equation and its general form are introduced, especially in the nonlinear region—for field corrosion monitoring purpose. Thirdly, through the design of low-power consumption real-time sensor systems for general corrosion monitoring, two types of smart corrosion sensors based on weak polarization analysis method are introduced with the application in marine environments.
