Methodology for Coated Infrastructure Inspection by Mobile Potentiostat

Methodology for Coated Infrastructure Inspection by Mobile Potentiostat
Available for download

A test methodology is shown for field application of electrochemical impedance spectroscopy (EIS). The method utilizes low-cost, accessible materials to secure a temporary solution cell to the infrastructure’s coated surface. A laptop computer provides the power source and operating system for the mobile potentiostat during EIS data collection. This data provides a quantitative measure of the coating condition. The objective of this work is to incorporate EIS testing into standard coatings inspection to estimate remaining service life for the intact coating, which improves coatings maintenance planning for facility owners.

The objective of this work is to incorporate EIS testing into standard coatings inspection to estimate remaining service life for the intact coating, which improves coatings maintenance planning for facility owners. The first field demonstrations took place at U.S. Army Corps of Engineers projects at OzarkJeta Taylor Lock and Dam and Wilbur D. Mills Lock and Dam along the Arkansas River. Tainter gate structures containing a three-coat vinyl system provided optimal conditions for EIS data collection. These results were compared to laboratory EIS data for vinyl coatings to estimate the remaining coating service life. An atmospheric red lead primer with Aluminum phenolic topcoat was also tested to demonstrate the method. This paper focuses on the most ideal circumstances for setting up and completing EIS testing in a single inspection. Variables to consider include coating type, exposure conditions, saturation level, access, and surface geometry/orientation. The mitigation of potential noise sources is also addressed to ensure accurate data and interpretation.

In order to simplify the measurement of electrochemical noise in field applications, three identical electrodes, one acting as reference electrode (RE), are often used. In this work, a measurement scheme, which employs two REs is proposed, which can reduce the error due to the RE's noise. An example of its implementation is also presented.

It was requested that exposure testing be completed on various high durability coatings products to evaluate gloss retention and color changes. Various systems were chosen to test, some with clear coats and some without. They were placed in cyclic UV/condensation testing, concentrated natural sunlight testing in Arizona, and outdoor exposure testing in South Florida.

Quality Assurance/Quality Control (QA/QC), often referred to as inspection, is critical to the success of a protective coating or lining project. Several parties can and do get involved in inspection including the owner, specifier, third party inspector, general contractor, painting contractor, equipment supplier, and coating manufacturer.
