Metal ceramic composite material with interphase network structure and preparation method of metal ceramic composite material
The invention is applicable to the technical field of metal ceramic composite materials, and provides a mutual reverse network structure metal ceramic composite material, which comprises a positive mold composite material and a reverse mold composite material, each of the positive mold composite material and the reverse mold composite material consists of a metal soft phase and a ceramic-rich hard phase, the structure is mutual reverse, the ceramic volume fraction in the ceramic-rich hard phase is 30-70vol. Metal in the ceramic-rich hard phase wraps ceramic particles to form a communication structure and is connected with the metal soft phase; a hard phase in the positive mold composite material is in a regular isolated column shape and is arranged in order, and a soft phase is in a continuous net shape; in the reverse mold composite material, the hard phase is in a continuous net shape, and the soft phase is in a regular isolated column shape and is arranged in order. The invention further provides a preparation method of the metal ceramic composite material with the interphase network structure. The ceramic column has the characteristic that the metal soft phase structure and the ceramic-rich hard phase structure are mutually inverse and designable, and the problems of inclination, mutual adhesion, breakage and other defects of the slender isolated ceramic column in the printing and post-processing processes are solved.
本发明适用于金属陶瓷复合材料技术领域，提供了一种互反网络结构金属陶瓷复合材料，包括正模复合材料和反模复合材料，均由金属软相及富陶瓷硬相组成，且结构互逆，富陶瓷硬相中陶瓷体积分数为30‑70vol.％，富陶瓷硬相内金属包裹陶瓷颗粒形成连通结构并与金属软相连接；正模复合材料中硬相呈规则孤立柱状且有序排列，软相呈连续网状；反模复合材料中硬相呈连续网状，软相呈规则孤立柱状且有序排列。本发明还提供了一种互反网络结构金属陶瓷复合材料的制备方法。本发明具有金属软相和富陶瓷硬相结构互逆可设计的特点，解决了细长孤立陶瓷柱在打印和后处理过程中出现倾斜、相互粘连和断折等缺陷的问题。
