Abstract
A corrosion sensor (1), apparatus for detecting corrosion of a surface incorporating the sensor, a structural assembly (1,21) incorporating the sensor and method for detecting corrosion of a surface employing the sensor are provided. The sensor comprises a thin flexible non-conducting substrate (18) for attachment to a surface subject to corrosive influence and an array of at least two thin flexible metallic electrodes (2,3,4) carried on the substrate wherein the electrodes are disposed closely adjacent one another so as to permit the generation of electric current by electrochemical action therebetween upon corrosion of the electrodes. The apparatus comprises one or more of the corrosion sensors (1) each being attachable to the surface so as to be exposed to the same corrosion conditions as the surface and means (6, 8, 10, 12, 14, 16) for measuring corrosion-induced electrochemical activity between the electrodes to provide an output indicative of the corrosion and the method provides a method of use of the apparatus described.
