Electrochemical noise and electrochemical impedance instrumentation studies.

摘要

Assessing the corrosion state of bare or coated metals can be accomplished by estimating an electrochemical parameter called polarization resistance or, more generally, corrosion resistance. This parameter can be estimated by analyzing the self-generated electrochemical potential and current fluctuations that are present during the corrosion process, or by the response of an electrochemical cell when a stimulus is applied in the form of a potential or current excitation. In this dissertation, alternative instrumentation techniques are proposed for both instrumentation methods, providing new possibilities for data analysis and instrumentation used in corrosion studies.
