Abstract: An ultrafine grain two-phase binderless tungsten carbide material is disclosed. The material contains, in weight percent, ditungsten carbide in the range of about 1 to about 10 percent, up to about 1.0 percent vanadium carbide and/or chromium carbide, up to about 0.2 percent cobalt, and the balance tungsten carbide, wherein the wear resistant material has a hardness of at least about 2,900 kg/mm 2 and a microstructure in which the tungsten carbide average grain size is no greater than about 0.3 microns. The material has a surprisingly good combination of wear resistance and hardness. Methods of making the material and articles made from the material are also disclosed.

Abstract: In one aspect, articles are described herein comprising wear-resistant claddings. An article described herein, in some embodiments, comprises a metallic substrate and a cladding adhered to the substrate, the cladding including a metal matrix composite layer comprising at least one hard particle tile having a pore structure infiltrated with matrix metal or matrix alloy. Infiltration of the pore structure of the hard particle tile by the matrix metal or alloy can render the tile fully dense or substantially fully dense.
