Abstract: Carbide pellets including relatively small amounts of metallic binder are produced by steps of pressing, comminuting, shaping and sintering. The carbide pellets may be used as wear resistant hard facing materials that are applied to various types of tools. The carbide pellets provide improved mechanical properties such as hardness and abrasiveness while maintaining required levels of toughness and strength.

Abstract: Composite coating materials comprising a hard carbide phase and a metallic binder that are resistant to molten metals such as aluminum are disclosed. The hard carbide phase of the composite coatings may comprise tungsten carbide, and the metallic binder may comprise a nickel-based alloy. A thin oxide layer comprising oxides of the binder metal may be provided on the surface of the composite coating. The composite coatings exhibit desirable non-wetting behavior when exposed to molten metals.
