Beschreibung
Zusammenfassung:	The invention relates to a part coated with a protective coating (2) that forms a thermal barrier comprising a ceramic first layer (22). The protective coating also comprises a second layer (23) present on the first layer comprising predominantly by weight a first feldspar ore having a melting point greater than or equal to 1010°C and having a thickness greater than or equal to 10 pm. The invention also relates to a process for manufacturing and using such a part. L'invention concerne une pièce revêtue d'un revêtement de protection (2) formant une barrière thermique comprenant une première couche céramique (22). Le revêtement de protection comprend en outre une deuxième couche (23) présente sur la première couche comprenant majoritairement en masse un premier minerai de feldspath ayant une température de fusion supérieure ou égale à 1010 °C et présentant une épaisseur supérieure ou égale à 10 pm. L'invention concerne aussi un procédé de fabrication et d'utilisation d'une telle pièce.
