  • Patent number: 4272211
    Abstract: A wear-resistant element, particularly in the form of a slab intended to be used as covering in areas exposed to excessive wear. The slab includes a hard wear metal of a hardness exceeding 400 Brinell, said wear-metal being in the form of granules which are embedded into a bonding agent consisting of synthetic resin, ceramic materials, rubber, or a combination of these materials. Preferably, the granules are arranged to agglomerate adjacent the wear face of the slab, whereas the concentration of wear metal towards the bottom of the slab is essentially nil. The resulting slab thus uses less amounts of the expensive wear-resistant material, and at the same time it is lighter than prior-art slabs and easier to manufacture.
