摘要: In one aspect of the invention, a wear resistant assembly has at least one hard insert disposed within a recess formed within a surface. A hard material substantially surrounds the hard insert and is also disposed within the surface. The hard material is separated from the insert by an intermediate material softer than both the insert and the hard material.

摘要: In one aspect of the invention, a pick comprises a steel body comprising a formed shank attached to a first end of the body and generally extending along a central axis of the body. An impact tip is secured to a second end of the steel body and comprises a carbide substrate attached to the second end of the steel body which is bonded to a superhard material. A composite material is bonded to an outer surface of the steel body and adapted to protect the steel from wear. The composite material comprises a plurality of superhard particles held within a matrix. The matrix comprises a superhard particle concentration of 40 to 80 percent by volume.

摘要: In one aspect of the invention, an attack tool has a wear-resistant base suitable for attachment to a driving mechanism. A first end of a generally frustoconical first cemented metal carbide segment bonded to the base. A second metal carbide segment is bonded to a second end of the first carbide segment at an interface opposite the base. The first end has a cross sectional thickness of about 0.250 to 0.750 inches and the second end has a cross sectional thickness of about 1 to 1.50 inches. The first cemented metal carbide segment also has a volume of 0.250 cubic inches to 0.600 cubic inches.

摘要: In one aspect of the invention, a tool has a wear-resistant base suitable for attachment to a driving mechanism and also a hard tip attached to an interfacial surface of the base. The tip has a first cemented metal carbide segment bonded to a superhard material at a non-planar interface. The tip has a height between 4 and 10 mm and also has a curved working surface opposite the interfacial surface. A volume of the superhard material is about 75% to 150% of a volume of the first cemented metal carbide segment.
