Title (EN) SHROUD AND METHOD FOR IMPLEMENTING ABRADABLE COATING
(FR) CARÉNAGE ET PROCÉDÉ DE MISE EN PLACE DE REVÊTEMENT ABRADABLE
(JA) アブレイダブルコーティングの施工方法及びシュラウド
Abstract:
(EN) A method for implementing an abradable coating comprising: a pattern-forming step S1 in which, using a slurry containing ceramic particles and solvent, a slurry pattern is formed on the surface of a thermal barrier coating layer; and a firing step S3 in which the slurry pattern formed on the surface of the thermal barrier coating layer is fired to form an abradable coating layer. A ceramic material included in the thermal barrier coating layer and ceramic particles included in the abradable coating layer are of the same type.
(FR) L'invention concerne un procédé de mise en place d'un revêtement abradable, comprenant : une étape de formation de motif (S1) pendant laquelle, à l'aide d'une pâte contenant des particules de céramique et un solvant, un motif de pâte est formé sur la surface d'une couche de revêtement barrière thermique; et une étape de cuisson (S3) pendant laquelle le motif de pâte formé sur la surface de la couche de revêtement barrière thermique est cuit afin de former une couche de revêtement abradable. Un matériau céramique inclus dans la couche de revêtement barrière thermique et des particules de céramique comprises dans la couche de revêtement abradable sont du même type.
(JA) アブレイダブルコーティングの施工方法は、セラミック粒子と溶媒とを含むスラリーを用いて、遮熱コーティング層の表面上にスラリーパターンを形成するパターン形成工程S1と、遮熱コーティング層の表面上に形成されたスラリーパターンを焼結して、アブレイダブルコーティング層を形成する焼成工程S3と、を備える。遮熱コーティング層に含まれるセラミック材料と、アブレイダブルコーティング層に含まれるセラミック粒子とは、同じ種類である。
