Corrosion monitoring under disbonded coatings
conference contribution
posted on 2022-09-29, 03:55 authored by Bob Varela, Mike Yongjun TanMike Yongjun Tan, Maria ForsythMaria Forsyth, Bruce HintonBruce HintonLocalized corrosion can occur under disbonded coatings threatening the safe operation of industry infrastructures such as underground oil and gas pipelines. Currently the assessment of localised corrosion under coating defects is a major technical challenge. The application of corrosion probes to monitor corrosion under disbonded coating also remains a difficulty. This paper presents a new corrosion sensor concept capable of electrochemically measuring corrosion rates under disbonded coatings on cathodically protected structures such as energy pipelines. Examples of its capabilities are illustrated with experimental data obtained in low conductivity aqueous solutions.
