Preparation method of ceramic material component with adjustable thermal expansion and product thereof
The invention discloses a preparation method of a ceramic material component with adjustable thermal expansion and a product thereof. The method comprises the following steps: preparation of ceramic slurry, preparation of a functionally gradient transition layer and photocuring 3D printing. Two ceramic materials which are resistant to high temperature and have positive thermal expansion coefficients are used as raw materials, a multi-ceramic structure with adjustable thermal expansion is designed, and the abnormal design of negative expansion, zero expansion and large-amplitude positive expansion in the height direction of ceramic material components of a two-dimensional isosceles triangle structure and a three-dimensional positive rectangular pyramid structure is achieved; a ceramic material 3D printing technology is used for preparing a multi-ceramic structure, and a functional gradient transition layer is used for releasing thermal mismatch stress to solve the problem of thermal mismatch between multi-phase ceramics. The ceramic material component prepared by the method has the characteristic of adjustable thermal expansion, and can be used under a high-temperature condition.
