摘要： Methods of forming and repairing earth-boring tools include providing wear-resistant material over a temporary displacement member to form 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 include a depth-of-cut control feature comprising a wear-resistant material. The depth-of-cut control feature is 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 include a depth-of-cut control feature extending over a temporary displacement member.

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.
