Abstract:
(EN) The thermal barrier coating is provided with a ceramic layer (120) formed on a heat-resistant alloy substrate and containing ceramic substance. The ceramic layer (120) has: a first dense layer (121); an intermediate porous layer (122) laminated on the first dense layer (121), having a higher density than the first dense layer (121), and in which many pores are formed; and a second dense layer (123) laminated on the intermediate porous layer (122) and having a lower density than the intermediate porous layer (122).
(FR) L'invention concerne un revêtement de protection thermique pourvu d'une couche de céramique (120) formée sur un substrat d'alliage résistant à la chaleur et contenant une substance en céramique. La couche de céramique (120) comprend : une première couche dense (121) ; une couche poreuse intermédiaire (122), stratifiée sur la première couche dense (121), et ayant une densité supérieure à celle de la première couche dense (121) et dans laquelle sont formés de nombreux pores ; et une seconde couche dense (123) stratifiée sur la couche poreuse intermédiaire (122) et ayant une densité inférieure à celle de la couche poreuse intermédiaire (122).
(JA) 遮熱コーティングは、耐熱合金基材上に形成され、セラミックを含むセラミック層(120)を備える。セラミック層(120)は、第一緻密層(121)と、第一緻密層(121)上に積層され、第一緻密層(121)よりも密度が大きく多数の気孔が形成された中間気孔層(122)と、中間気孔層(122)上に積層され、中間気孔層(122)よりも密度が小さい第二緻密層(123)とを有する。
