摘要： A method for applying hardfacing to teeth on a drill bit is disclosed. The method includes applying the hardfacing to at least one of the teeth so as to have a thickness selected to correspond to a position about exterior surface of the tooth. In one embodiment, the hardfacing thickness is increased near the crest of the tooth, and is decreased near the root of the tooth on at least one flank of the tooth. In one embodiment, the thickness is selected by controlling the powder flow rate in a plasma transferred arc welding system. In another embodiment an angle subtended by flanks of the tooth is selected to provide increased strength to the tooth, and the hardfacing is applied to the tooth to cause exterior surfaces of the hardfacing corresponding to the flanks to subtend an angle selected to provide increased penetration of the tooth through earth formations while drilling.

摘要： Polycrystalline ultra-hard compact constructions comprise a polycrystalline ultra-hard compact having a polycrystalline ultra-hard body attached to a substrate. A support member is attached to the compact by a braze material. The support member can have a one-piece construction including one or more support sections. The support member has a first section extending axially along a wall surface of the compact, and extending circumferentially along a portion of the compact. The support member can include a second section extending radially along a backside surface of the compact, and/or a third section extending radially along a front side surface of the compact. In one embodiment, the support member includes a second and/or third section and the compact disposed therein is in an axially compressed state. The support member is interposed between the compact and an end-use device, and improves the compact attachment strength to an end-use device when compared to conventional compacts.

摘要： Seals of this invention comprise an annular elastomeric ring-shaped body having a dynamic surface disposed along a first body portion, the dynamic surface comprising at least two surface elements that project outwardly therefrom to provide multiple barriers to fluid and debris migration thereacross when placed into contact with a rock bit rotary dynamic surface. The seal dynamic surface includes a recessed portion disposed between the surface elements, and a static seal surface disposed along a second body portion. At least one of the surface elements includes a wear surface that is formed from a material that is more wear resistant than materials that are used to form a remaining portion of the seal. A preferred wear surface is one formed from a composite material comprising a fabric of nonelastomeric polymeric material that is bonded together with an elastomeric material. Seals of this invention provide improved properties of both wear resistance and sealability when compared to conventional seals having a single dynamic seal surface.
