Preparation method of ceramic-based composite material
The invention discloses a preparation method of a ceramic-based composite material, which comprises the following steps: 1, placing a target material in a water-cooled copper crucible in a vacuum chamber, and placing a preform above the target material; 2, heating the preform by adopting an electron beam; and 3, heating an evaporation target material by adopting an electron beam, and preparing a ceramic matrix and a coating with integrated structure and function on the prefabricated body. The method is high in efficiency and short in manufacturing period; electron beams can enhance vapor infiltration, and the prepared composite material is high in density; the fibers are not damaged by preparation temperature and atmosphere, and the prepared composite material is good in mechanical property; the preform is not limited, can adopt carbon fibers, carbide fibers, oxide fibers and the like, and can adopt various forms such as fibrofelt, two-dimensional forms, three-dimensional forms and the like; the ceramic matrix is not limited, and one or more ceramic matrixes of carbon, carbide, oxide, boride, silicide and the like can be adopted; the ceramic matrix is high in designability, and the composite ceramic matrix and the coating which are integrated in structure and function can be prepared.
本发明公开了一种陶瓷基复合材料的制备方法，包括以下步骤：一、将所靶材置于真空室中的水冷铜坩埚中，将预制体置于靶材的上方；二、采用电子束加热预制体；三、采用电子束加热蒸发靶材，在预制体上制备结构功能一体化的陶瓷基体及涂层。本发明效率高、制造周期短；电子束能够增强气相渗透，制备的复合材料致密度高；制备温度以及气氛不损伤纤维，制备的复合材料力学性能好；预制体不受限制，可采用碳纤维、碳化物纤维、氧化物纤维等，可采用纤维毡、二维、三维等各种形式；陶瓷基体不受限制，可采用碳、碳化物、氧化物、硼化物、硅化物等一种或多种陶瓷基体；陶瓷基体可设计性强，能够制备出结构功能一体化的复相陶瓷基体及涂层。
