Novel wear-resistant cast surface composite materials have been developed recently at our laboratories by combining conventional metal casting technology with the technology of refractory metal carbides in the form of fibers and textiles. Metals and alloys which hitherto were considered wear-prone, e. g., aluminum alloys, can be used as matrix materials for cast surface composites which exhibit wear properties comparable to those associated with traditional sintered carbide materials. These new-wear-resistant materials can be produced simply by casting metal in a mold or die lined with a refractory metal carbide textile. During casting, contact of the molten matrix material with good wetting, permits interfacial bond formation and penetration of the textile by the molten alloy. After solidification, the surface has a unique duplex microstructure consisting of 75– 80 volume percent of hard carbide phase MC (M = Ta, Ti or W) dispersed within the matrix alloy to a depth from the surface determined by the type of textile used.
