Patent ID: 8388723

Claim:
An abrasive wear-resistant material comprising the following materials in pre-application ratios: a matrix material, the matrix material comprising between about 20% and about 60% by weight of the abrasive wear-resistant material, the matrix material comprising at least 75% nickel by weight, the matrix material having a melting point of less than about 1100° C.; a plurality of −20 ASTM mesh sintered tungsten carbide pellets substantially randomly dispersed throughout the matrix material, the plurality of sintered tungsten carbide pellets comprising between about 30% and about 55% by weight of the abrasive wear-resistant material, each sintered tungsten carbide pellet comprising a plurality of tungsten carbide particles bonded together with a binder alloy, the binder alloy having a melting point greater than about 1200° C.; and a plurality of −40 ASTM mesh cast tungsten carbide granules substantially randomly dispersed throughout the matrix material, the plurality of cast tungsten carbide granules comprising less than about 35% by weight of the abrasive wear-resistant material; wherein each sintered tungsten carbide pellet of the abrasive wear-resistant material has a first average hardness in a central region of the pellet and a second hardness in a peripheral region of the pellet, the second hardness being greater than about 99% of the first average hardness.
