摘要： A method includes disposing a braze material between a first body and a second body. The braze material includes a first composition and a second composition. The second composition has a melting point higher than the first composition. The braze material may be heated to a brazing temperature between the melting points of the first and second materials and maintaining the braze material at the brazing temperature for a period of time to transform a transient liquid phase to a solid phase, forming a bond between the first body and the second body. A braze material for securing solid bodies includes a first composition and a second composition. The first composition includes at least one element selected from the group consisting of indium, tin, zinc, and magnesium. An earth-boring tool includes a first body, a second body, and a braze material bonding the second body to the first body.

摘要： Methods of repairing earth-boring tools may involve providing wear-resistant material over a temporary displacement member to repair a cutting element pocket in a body and a depth-of-cut control feature using the wear-resistant material. In some embodiments, the wear-resistant material may comprise a particle-matrix composite material. For example, a hardfacing material may be built up over a temporary displacement member to form or repair a cutting element pocket and provide a depth-of-cut control feature. Earth-boring tools may include a depth-of-cut control feature comprising a wear-resistant material. The depth-of-cut control feature may be configured to limit a depth-of-cut of a cutting element secured within a cutting element pocket partially defined by at least one surface of the depth-of-cut control feature. Intermediate structures formed during fabrication of earth-boring tools may include a depth-of-cut control feature extending over a temporary displacement member.

摘要： Magnetic sample holders for abrasive operations include an array of magnets embedded in a matrix material. Each magnet of the array is positioned between about 0 mm and about 4 mm from at least one adjacent magnet of the array. Exposed surfaces of the magnets of the array are coplanar with a planar working surface of the matrix material. Methods of forming a polycrystalline diamond compact element include magnetically securing an alloy sample to an array of magnets embedded in a matrix. Each of the magnets of the array is within about 4 mm of at least one adjacent magnet of the array. A portion of the alloy sample is abraded away, and the alloy sample is positioned proximate to diamond grains and a substrate. The alloy sample, diamond grains, and substrate are subjected to a high pressure/high temperature process to sinter the diamond grains.

摘要： A downhole tool for use in wellbores comprises a layer of hydrophobic material over a body, wherein the layer of hydrophobic material comprises a transition metal boride having a higher hydrophobicity than the body. The downhole tool may comprise a body having a composition and the layer of hydrophobic material comprising a discontinuous phase of the transition metal binder dispersed within a first continuous phase comprising a metal binder. The layer of material may be chemically bonded to the body. An interface between the body and the layer of material may comprise the transition metal boride dispersed within a second continuous phase comprising the metal binder and the composition of the body. Methods of forming downhole tools include forming such a layer of material at a surface of a body of a downhole tool.

摘要： A component for a downhole tool includes a rotor and a hardfacing precursor. The hardfacing precursor includes a polymeric material, hard particles, and a metal. A hydraulic drilling motor includes a stator, a rotor, and a sintered hardfacing material on an outer surface of the rotor or an inner surface of the stator. Methods of applying hardfacing to surfaces include forming a paste of hard particles, metal matrix particles, a polymeric material, and a solvent. The solvent is removed from the paste to form a sheet, which is applied to a surface and heated. A component for a downhole tool includes a first hardfacing material, a second hardfacing material over the first hardfacing material and defining a plurality of pores, and a metal disposed within at least some of the pores. The metal has a melting point lower than a melting point of the second hardfacing material.
