Abstract

Elément de détection de la corrosion ou de la possibilité de corrosion d’une pièce L’invention concerne un élément de détection (1) de la corrosion ou de la possibilité de corrosion d’une pièce, comprenant des particules (10) encapsulant un agent modificateur (12) qui est apte à être libéré en présence d’un composé associé à la corrosion de la pièce de sorte à éliminer chimiquement une partie au moins de l’élément de détection et à modifier ainsi la propagation du signal physique (SO) dans cet élément. Figure pour l’abrégé : Fig. 1.Element for detecting corrosion or the possibility of corrosion of a part The invention relates to an element (1) for detecting corrosion or the possibility of corrosion of a part, comprising particles (10) encapsulating a modifier (12) which is capable of being released in the presence of a compound associated with the corrosion of the workpiece so as to chemically eliminate at least part of the sensing element and thereby modify the propagation of the physical signal (SO) in this element. Figure for abstract: Fig. 1.
