    Cathodic and Anodic Protection: Effect of Volatile Corrosion Inhibitors on Cathodic Protection

    Published: December 01, 2018
    Author(s): Khalil M. Abed, Cortec Middle-East, Dubai, United Arab Emirates Calvin R. Pynn, Prydwen International, Inc., Collingwood, Ontario, Canada

    Volatile corrosion inhibitors (VCIs) and cathodic protection (CP) are applied jointly to effectively mitigate corrosion in both the electrolytic and vapor-phase exposures on the soil-side of tank bottoms. The electrochemical characteristics of available VCI...
