TiC/graphite film layered composite material and preparation method thereof
The invention relates to the field of inorganic non-metallic materials, and discloses a TiC/graphite film layered composite material and a preparation method thereof. The composite material is composed of, by volume, 23.2-84.9% of TiC ceramic phase and 15.1-76.8% of graphite phase, wherein graphite and TiC are alternately distributed layer by layer in the composite material and arranged in a perfect orientation mode. The preparation method comprises the three steps of Ti foil pretreatment, layer-by-layer stacking of the Ti foil and the graphite film and subsequent vacuum hot pressing sintering. The method is simple in process and low in cost, and the prepared material is uniform in microstructure and high in density. In addition, the preparation method is also suitable for preparation of WC, Cr2C3, MoC, ZrC and other ceramic and graphite film composite materials, and therefore the preparation method of the carbide ceramic/graphite film layered composite material is greatly expanded.
本发明涉及无机非金属材料领域，公开了一种TiC/石墨膜层状复合材料及其制备方法，该复合材料按体积分数计，由23.2～84.9％的TiC陶瓷相和15.1～76.8％的石墨相组成，石墨和TiC在复合材料中逐层交替分布，并呈完美取向排列；其制备方法由Ti箔的预处理、Ti箔与石墨膜的逐层堆叠及后续的真空热压烧结三个步骤组成。本发明工艺简单，成本低廉，且制备出的材料微观结构均匀，致密度高。另外，本发明也适合WC、Cr2C3、MoC、ZrC等陶瓷与石墨膜复合材料的制备，因此大大扩展了碳化物陶瓷/石墨膜层状复合材料的制备方法。
