摘要： Earth-boring tools for drilling subterranean formations include a particle-matrix composite material comprising a plurality of silicon carbide particles dispersed throughout a matrix material, such as, for example, an aluminum or aluminum-based alloy. In some embodiments, the silicon carbide particles comprise an ABC—SiC material. Methods of manufacturing such tools include providing a plurality of silicon carbide particles within a matrix material. Optionally, the silicon carbide particles may comprise ABC—SiC material, and the ABC—SiC material may be toughened to increase a fracture toughness exhibited by the ABC—SiC material. In some methods, at least one of an infiltration process and a powder compaction and consolidation process may be employed.

摘要： A method of hardfacing a bit using a hardfacing sheet. The hardfacing sheet includes a hardfacing composition in a carrier material. The sheet is placed on a portion of the bit body, the sheet is heated at a designated spot using a localized heating source. At the same time, oxygen is substantially purged from the zone adjacent the designated spot. The heat debinds the carrier material from the sheet leaving the hardfacing composition. Continued heating transforms the hardfacing composition into hardfacing that is fused to the bit body.
