    Abstract

    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 general corrosion. Thanks to the advancement in coupled multielectrode array sensors (CMAS) technology, localized corrosion rates can now be quantitatively measured. If interfaced with controllers, CMAS probes can be used to automatically control the dosing of corrosion inhibitors and reduce the cost for corrosion control. This paper presents an overview for the CMAS technology and the experimental data that verifies the working principles of the CMAS for localized corrosion rate measurement.
