摘要：
A highly abrasive wear metal matrix composite hardfacing material for downhole tools is disclosed. The hardfacing material may comprise a matrix of a softer material with high hardness, such as amorphous nanocomposite steel alloys, and one or more hard component materials. The hard component materials may comprise sintered tungsten carbide, monocrystalline WC, polycrystalline WC, and the additional component of spherical cast tungsten carbide. Alternatively, a matrix of softer material, hard component materials and crushed cast tungsten carbide may be used.
