    A Review of Coupled Multielectrode Array Sensors for Corrosion Monitoring and a Study on the Behaviors of the Anodic and Cathodic Electrodes (STP 1506)

    Published: January 01, 2009
    Author(s): L. Yang, Southwest Research Institute; K.T. Chiang, Southwest Research Institute

    Localized corrosion is often the cause of many failures and unplanned shutdowns in industry. For example, statistics have shown that more than 80 % of the corrosion-induced failures in the chemical processing industry are due to localized corrosion, rather than...

    Electrochemical Quartz Crystal Microbalance Technique to Monitor External Polymeric Pipeline Coatings (STP 1506)

    Published: January 01, 2009
    Author(s): S. Papavinasam, Natural Resources Canada; M. Attard, Natural Resources Canada; R.W. Revie, Natural Resources Canada

    Electrochemical Quartz Crystal Microbalance (EQCM) can be used to monitor changes in several material properties, including mass, electrochemical, viscosity, adsorption, and deposition. In this paper, EQCM was evaluated to determine if it can monitor changes to...

    Electrochemical Impedance Spectroscopy Measurement during Cathodic Disbondment Experiment of Pipeline Coatings (STP 1506)

    Published: January 01, 2009
    Author(s): S. Papavinasam, Natural Resources Canada; M. Attard, Natural Resources Canada; R.W. Revie, Natural Resources Canada

    Modified cathodic disbondment (CD) experiments were carried out over a period of 14 months using 13 coatings used to protect the external surfaces of oil and gas pipelines. During the experiments, electrochemical impedance spectroscopy (EIS) data were recorded,...

    Development of Electrochemical Standards for Corrosion Testing (STP 1506)

    Published: January 01, 2009
    Author(s): S.W. Dean, Dean Corrosion Technology, Inc.

    Although the understanding that corrosion is an electrochemical process has been known for almost a century, the exploitation of electrochemical techniques for corrosion testing has largely occurred in the past four decades. The development of standard...

    Measuring the Repassivation Potential of Alloy 22 Using the Potentiodynamic-Galvanostatic-Potentiostatic Method (STP 1506)

    Published: January 01, 2009
    Author(s): K.J. Evans; R.B. Rebak, Lawrence Livermore National Laboratory

    Traditionally, the susceptibility of Alloy 22 (N06022) to suffer crevice corrosion has been measured using the Cyclic Potentiodynamic Polarization (CPP) technique (ASTM G 61). When the alloy is not very susceptible to crevice corrosion, the values of...
