ABSTRACT

A survey and review of recent patents on electrochemical methods for corrosion monitoring from 1999 to 2009 are presented in this paper. The patents were classified into 4 groups according to different electrochemical theories, which are potential, polarization, electrochemical impedance and electrochemical noise. A future outlook of the development on new research aspects particularly on methods based on electrochemistry is prospected.

Keywords:

Corrosion monitoring, electrochemical potential, polarization, electrochemical impedance spectroscopy, electrochemical noise.
