摘要:
A production of a cast workpiece having increased wear protection in regions, wherein ceramic particles having an average grain size of between 0.2 and 4 mm are mixed with at least one binding agent. Said mixture is applied to a heat-resistant fiber mat at a particular layer thickness, whereby a two-layer structure arises. After hardening of the binding agent, an insert (9) is constructed from the two-layer structure, the shape thereof corresponding to the shape of a surface region of the cast workpiece to be protected. The insert (9) is applied in the casting cavity (8) at the location corresponding to the surface region of the cast workpiece to be protected. The casting cavity (8) is finally filled with casting material, wherein the ceramic particles in the insert (9) are embedded in the casting material.
