The invention relates to the field of materials, in particular to a preparation method for a metal-coated ceramic fragment type novel material. The preparation method comprises the following steps that (1) a to-be-coated ceramic material is cut and broken; (2) ceramic fragments are cleaned for standby application; (3) matrix metal and the ceramic fragments which are used for casting forming are weighed according to the set mass ratio; (4) the surfaces of the ceramic fragments are coated with metal layers used for adjusting the average density of the ceramic fragments; and (5) the metal-coatedceramic fragment type novel material is prepared through foundry casting. The surfaces of the ceramic fragments are coated with the metal layers for adjusting the density of the ceramic fragments, sothat the average density of the ceramic fragments and the metal layers are larger than, or equal to or smaller than the density of matrix metal liquid, and the prepared metal-coated ceramic fragment material has ductility, conductivity, machinability and the like of metal, also has the characteristics of high hardness, high abrasion resistance and high strength of ceramic and can be widely appliedto an aircraft carrier deck, an abrasion resistant platform, a high-strength platform, abrasion-resistant firmware and the like.
