Preparation method of ceramic-based composite material component with abradable coating and the component
The invention belongs to the field of surface treatment of ceramic-based composite materials, and relates to a preparation method of a ceramic-based composite material component with an abradable coating and the component, solving the problems that ceramic-based composite material components with abradable coatings in the prior art are poor in mechanical performance, weak in oxidation resistance,short in service lifetime and poor in matching performance between the coatings and the ceramic-based composite materials. By machining a certain number of grooves and blind holes in the surface of the matrix of the ceramic-based composite material, the bonding force between the abradable coating and the matrix of the ceramic-based composite material is improved, making connection tighter, achieving higher durability, and further improving mechanical performance, oxidation resistance and service lifetime of the component.
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及盲孔，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，进一步提升此类构件的力学性能、抗氧化性能及构件使用寿命。
