Varela, F, Tan, MYJ, Forsyth, M and Hinton, B 2014, Corrosion monitoring under disbonded coatings, in Corrosion and Prevention : Proceedings of the 2014 Annual Conference of the Australasian Corrosion Association, Australasian Corrosion Association, [Darwin, Northern Terroritory], pp. 1-9.
Localized 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.
