Abstract

L'invention concerne un composant (12) comportant une couche (11) formant la surface (13), composée de plusieurs strates (14a, 14b). Selon l'invention, seules certaines strates (14b) de la couche (11) sont pourvues de nanoparticules (15b) d'un ou plusieurs colorants prédéterminés. De manière avantageuse, les strates colorées (14b) sont ainsi rendues visibles en cas d'usure (18), ce qui permet d'évaluer l'état d'usure de la couche (11) par une simple inspection optique. L'invention concerne également un procédé de fabrication de telles couches de préférence composées de précurseurs précéramiques.
