摘要： A cutting tool includes a supporting body and a cBN or PCD cutting edge tip attached to the supporting body via a 5-150 μm braze joint. The supporting body is cemented carbide having 3-25 wt % of a metallic binder, optionally up to 25 wt % of carbides or carbonitrides of one or more elements of group 4, 5, or 6, and the rest WC. The metallic binder includes at least 40 wt % Ni, and the braze joint has, in the order from the supporting body, a first layer of TiC situated next thereto, with an average thickness of 10-400 nm, a second layer, with an average thickness of 0.5-8 μm, having in average at least 5 wt % metallic Ni, in average 25-60 wt % metallic Cu and in average 15-45 wt % metallic Ti, and a third layer, with an average thickness of 4-145 μm, having metallic Ag and metallic Cu.

摘要： Methods of forming at least a portion of an earth-boring tool include providing particulate matter including a hard material in a mold cavity, melting a metal and the hard material to form a molten composition comprising a eutectic or near-eutectic composition of the metal and the hard material, casting the molten composition to form the at least a portion of an earth-boring tool within the mold cavity, and providing an inoculant within the mold cavity. Methods of forming a roller cone of an earth-boring rotary drill bit include forming a molten composition, casting the molten composition within a mold cavity, solidifying the molten composition to form the roller cone, and controlling grain growth using an inoculant as the molten composition solidifies. Articles including components of earth-boring tools are fabricated using such methods.

摘要： A hardfacing disposable on a surface of a component, such as a wellsite component, is disclosed. The hardfacing comprises a surface portion and a bottom portion with a segregation line defined therebetween. The surface portion and the bottom portion each include a matrix phase including a matrix composition made of a metal alloy and a hard phase distributed in the matrix phase. The hard phase may include an abrasion-resistant composition made of a hard material (e.g., vanadium carbide). The surface portion has a first concentration of the abrasion-resistant composition and the bottom portion has a second concentration of the abrasion-resistant composition with the first concentration being greater than the second concentration such that a wear resistant surface is defined on the surface of the component.
