Tungsten-uranium composite material and preparation method thereof

The invention discloses a tungsten-uranium composite material and a preparation method thereof.The high-volume-fraction tungsten particle reinforced uranium and uranium alloy composite material is prepared by combining a sintering method with a self-exhaust infiltration technology, and the method comprises the steps of tungsten framework prefabricated body preparation, infiltration mold and coating design, the self-exhaust infiltration technology and the like. Uranium and uranium alloy can fully infiltrate into pores in the tungsten skeleton, and the infiltration effect is excellent. 本发明公开了一种钨铀复合材料及其制备方法，通过烧结法结合自排气浸渗技术，制备出了高体积分数钨颗粒增强的铀及其合金复合材料，所述方法包括钨骨架预制体制备、浸渗模具及涂层设计、自排气浸渗工艺等步骤，铀及铀合金可充分渗入钨骨架内部孔隙，浸渗效果优异。
