Preparation method of ceramic matrix composite component with abradable coating and component
The invention belongs to the field of surface treatment of ceramic matrix composite materials and relates to a preparation method of a ceramic matrix composite component with an abradable coating andthe component. The problem that an existing ceramic matrix composite component with an abradable coating is poor in mechanical property, poor in oxidation resistance and short in service life, and thethermal matching property of the abradable coating and the ceramic matrix composite is poor is solved. By machining a certain number of small counter bores with specific diameters in the surface of the ceramic matrix composite matrix, the binding force of the abradable coating and the ceramic matrix composite matrix is enhanced, the abradable coating and the ceramic matrix composite matrix are connected more tightly, durability is higher, the mechanical property and 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特定直径小型沉孔，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。
