Machining process for parts of metal matrix ceramic composite material
The invention belongs to the field of material machining, and discloses a machining process of parts of a metal matrix ceramic composite material. The machining process comprises the following steps that a ceramic preform is prepared, sintering is conducted, a rough blank of the ceramic preform is machined, a casting blank of the metal matrix ceramic composite material is prepared, and mechanicalmachining and heat treatment are conducted. Compared with the prior art, with the technical scheme, the machining process has the advantages that the forming and machining difficulty of the precisionparts of the metal matrix ceramic composite material can be greatly lowered, the machining cost is lowered, the production cycle is shortened, in addition, the prepared ceramic preform cannot have problems such as cracking, deformation and non-through burning, and the compositing of the ceramic preform and a metal matrix is facilitated.
本发明属于材料加工领域，公开了一种金属基陶瓷复合材料零件的加工工艺，包括以下步骤：制备陶瓷预制体、烧结、陶瓷预制体粗坯加工、制备金属基陶瓷复合材料铸坯、机械加工和热处理。与现有技术相比，本发明所述技术方案可大大降低金属基陶瓷复合材料精密零件的成型及加工难度，降低加工成本，缩短生产周期，另外，本发明制备的陶瓷预制体不会出现开裂、变形、烧不透等问题，利于陶瓷预制体与金属基进行复合。
