Electrochemical Measurement of Low Corrosion Rates

Abstract

Materials with corrosion rates of 0.1 mpy or less are required in many applications. In this investigation, application of linear polarization to measurement of low corrosion rates is examined. Also, two new electrochemical techniques are derived theoretically and verified experimentally. These methods can measure accurately corrosion rates less than 0.0005 mpy and require 20 minutes or less to perform.
