<p>Disclosed are an apparatus, a method and a cast composite component. The disclosure notes that composite materials are useful for wear or impact resistance, but combining materials with different characteristics can be problematic due to different materials often having different coefficients of thermal expansion, densities and melting points. The apparatus comprises a casting mould (500), retaining structure (502) and a plurality of loose ceramic particles (504). The casting mould (500) has an interior surface that is structurally resistant to molten metal. The retaining structure (502) is permeable to molten metal and is structurally resistant to molten metal. The retaining structure (502) is in contact with the interior surface of the casting mould (500). The plurality of loose ceramic particles (504) are secured in place in the casting mould (500) in part by the retaining structure (502). The retaining structure (502) is impermeable to the ceramic particles (504).</p> |
