Manufacturing method of ceramic-metal composite structure and ceramic-metal composite structure
The invention discloses a manufacturing method of a ceramic-metal composite structure and the ceramic-metal composite structure, and the manufacturing method comprises the following steps: producing a ceramic green body through an additive manufacturing method, so that a fixed cavity is formed in the ceramic green body, and a buffer layer green body is formed on the inner wall of the fixed cavity; sintering the ceramic body to obtain a ceramic structure and a buffer layer in the ceramic structure; the ceramic structure is subjected to heat preservation, and molten metal liquid is injected into a fixing cavity; and the ceramic-metal composite structure is obtained by adopting a gradual cooling mode. The ceramic body is manufactured in an additive manufacturing mode, the fixing cavity with the complex shape and structure can be formed in the ceramic body, and the shape of molten metal liquid cured in the fixing cavity is matched with the shape of the curing cavity; moreover, the buffer layer can adapt to the shape of the fixed cavity, the cooling shrinkage force of the molten metal liquid acts on the buffer layer, the shrinkage force is prevented from directly acting on the outer-layer ceramic, pulling of the molten metal to the outer-layer ceramic is reduced, the shock resistance of the ceramic is improved, and the service life of the ceramic is prolonged.
本发明公开了一种陶瓷金属复合结构的制造方法及陶瓷金属复合结构，包括以下步骤：通过增材制造的方法生产陶瓷坯体，使得陶瓷坯体内形成固定腔，并使得固定腔的内壁形成有缓冲层坯体；对陶瓷坯体进行烧结，得到陶瓷结构以及陶瓷结构内部的缓冲层；对将陶瓷结构进行保温，将熔融金属液注入固定腔；采用逐步降温的方式得到陶瓷金属复合结构。通过增材制造的方式制造陶瓷坯体，能够在陶瓷坯体内形成形状及结构复杂的固定腔，熔融金属液在固定腔内固化后的形状与固化腔的形状相匹配；而且，缓冲层能够适应固定腔的形状，熔融金属液冷却收缩的力作用于缓冲层，避免收缩力直接作用于外层陶瓷，减小熔融金属对外层陶瓷拉扯，提高陶瓷的抗冲击性能及使用寿命。
