  • Abrasion and impact resistant composite castings for working in condition of wear and high dynamic loads
    Patent number: 8241761
    Abstract: A composite casting for a wear resistant surface, comprising a base composed of a ductile material; and a plurality of wear resistant inserts embedded in said base and composed of a carbide-containing wear resistant alloy which after casting is hot strained by forging or rolling, said inserts being arranged in said base rows so that said inserts of each subsequent one of said rows overlap gaps between said inserts of a preceding one of said rows and (or) said inserts should be positioned with their side bases at a degree (relative to the movement of the abrasive material) of no less than 20°, which would prevent the wear of the ductile base of the composite castings.
