Abstract
Ensemble pour la détection de la corrosion ou de la possibilité de corrosion d’une pièce L’invention concerne un ensemble (20) pour la détection de la corrosion ou de la possibilité de corrosion d’une pièce (22), comprenant un élément de détection (1), ainsi qu’une pièce incorporant des particules encapsulant un agent modificateur 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 dans cet élément. Figure pour l’abrégé : Fig. 1.
