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.
