摘要 |
An air seal 10 is illustrated as used in a gas turbine engine. The seal 10 includes at least a seal substrate 12, a relatively dense. erosion resistant ceramic layer 16 applied over a bond coat 14, and an abradable ceramic layer 18 applied in a local area over the dense ceramic layer 16. The abradable ceramic interacts with a component moving relative to the seal, such as a turbine blade that moves relative to the seal, and cooperates with the moving component to provide sealing and thermal insulation. <IMAGE> |
