| titleOfInvention | Composite-structure environmental barrier coating, preparation method and application thereof, and aero-engine |
| abstract | Hair brushThe invention relates to a composite structure environmental barrier coating, a preparation method and application thereof, and an aeroengine, and belongs to the field of materials. The preparation method comprises the following steps: adopting a plasma spraying-physical vapor deposition method to prepare a Si coating, a mullite coating and Yb with a layer/column composite structure on the surface of a substrate layer in sequence 2 SiO 5 And (4) coating. The raw material of the matrix layer contains a SiC/SiC composite material. The preparation method is simple, easy to operate, short in time consumption and high in deposition efficiency, and can realize gas, liquid and solid multi-phase deposition. The prepared composite structure environmental barrier coating not only has high compactness, but also can effectively release thermal stress in the high-low temperature thermal cycle process, thereby integrally improving the thermal cycle performance of the environmental barrier coating. The hot-end component can meet the use requirements of the hot-end component of the engine. The aircraft engine containing the composite structure environmental barrier coating has good high-temperature resistance. |
