| titleOfInvention | Preparation method of ceramic material component with adjustable thermal expansion and product thereof |
| abstract | The invention discloses a preparation method of a ceramic material component with adjustable thermal expansion and a product thereof, wherein the method comprises the following steps: preparing ceramic slurry, preparing a functional gradient transition layer and carrying out photocuring 3D printing. The invention takes two ceramic materials with high temperature resistance and positive thermal expansion coefficient as raw materials, designs a multi-ceramic structure with adjustable thermal expansion, and realizes the supernormal design of negative expansion, zero expansion and large-amplitude positive expansion in the height direction of ceramic material components of a two-dimensional isosceles triangular structure and a three-dimensional regular rectangular pyramid structure; the ceramic material 3D printing technology is used for preparing a multi-ceramic structure, and the functional gradient transition layer is applied to release thermal mismatch stress so as to solve the problem of thermal mismatch among multi-phase ceramics. The ceramic material member prepared by the invention has the characteristic of adjustable thermal expansion and can be used under the high-temperature condition. |
