Preparation method of ceramic matrix composite material component with abradable coating layer and component
The invention belongs to the field of surface treatment of ceramic-based composite materials. The invention relates to a preparation method of a ceramic matrix composite material component with an abradable coating layer and the component. The problems that an existing ceramic matrix composite material component with an abradable coating layer is poor in mechanical property, poor in oxidation resistance and short in service life, and the thermal matching property of the abradable coating layer and a ceramic matrix composite material is poor are solved. By processing a certain number of groovesin the surface of the ceramic matrix composite material matrix, the binding force of the abradable coating layer and the ceramic matrix composite material matrix is enhanced, so that the abradable coating layer and the ceramic matrix composite material matrix are connected more tightly, the durability is higher, the mechanical property and the oxidation resistance of the component are improved, and the service life of the component is prolonged.
本发明属于陶瓷基复合材料表面处理领域，涉及一种具有可磨耗涂层的陶瓷基复合材料构件的制备方法及构件，解决现有具有可磨耗涂层的陶瓷基复合材料构件存在的力学性能差、抗氧化性能弱构件使用寿命短及可磨耗涂层与陶瓷基复合材料热匹配性较差的问题，通过在陶瓷基复合材料基体表面加工一定数量的凹槽，增强可磨耗涂层与陶瓷基复合材料基体的结合力，使二者连接更为紧密，耐久性更高，提升了此类构件的力学性能、抗氧化性能及构件使用寿命。
