Micro-laminated gradient ceramic/metal composite material and preparation method thereof
The invention relates to a micro-laminated gradient ceramic/metal composite material and a preparation method thereof, and belongs to the technical field of ceramic-based bionic composite materials. The preparation method comprises the following steps: firstly, preparing a micro-laminated gradient porous ceramic preform through the technological processes of slurry preparation, layer-by-layer casting, bidirectional freezing pouring and vacuum freeze drying, and then filling pores of the ceramic preform with a metal material. The ceramic material is one or more of Al2O3, B4C, SiC, Si3N4 and TiB2, and the metal is aluminum, magnesium, iron or an alloy taking the aluminum, the magnesium and the iron as a matrix. The composite material disclosed by the invention has the beneficial effects that the composite material has the multi-stage micro-lamination gradient structure formed by alternately laminating soft and hard materials, can combine the effects of the multi-stage lamination and the gradient structure in the aspect of performance enhancement, and has the advantages of light weight, high strength, high toughness and excellent impact resistance and damage resistance.
