Disclosed is a thermal barrier coating material for coating a gas turbine member that provides a higher thermal barrier property and a higher peeling resistance. The thermal barrier coating material comprises a metal binding layer laminated on a base material and a ceramic layer laminated on the metal binding layer wherein the ceramic layer comprises partially stabilized ZrO2 which is partially stabilized by adding both Dy2O3 and Yb2O3.
L'invention concerne un matériau de revêtement barrière thermique destiné au revêtement d'un composant de turbine à gaz et dont les propriétés de barrière thermique et de résistance au décollement sont excellentes. Le matériau de revêtement barrière thermique est constitué d'une couche de liaison métallique laminée sur un matérieau de base et une couche céramique laminée sur la couche de liaison métallique, ladite couche céramique contenant du ZrO2 qui est partiellement stabilisé par addition de Dy2O3 and Yb2O3.
