Publication number: 20140123564Abstract: Abrasive compacts, in particular ultrahard polycrystalline abrasive compacts, are made under high pressure/high temperature conditions and are characterized in that they include a coarser grained fraction of ultrahard particles distributed non-percolatively throughout a finer grained fraction of ultrahard particles, which may be regarded as a finer grained ultrahard particle matrix, in such a way that the individual coarser grains are largely isolated from one another. It therefore performs as a matrix of highly wear resistant finer grained material interspersed with larger grains, offering a structure that has advantageous wear and impact performance over the behaviours of the two components individually or otherwise combined.Type: ApplicationFiled: November 4, 2013Publication date: May 8, 2014Applicant: ELEMENT SIX (PRODUCTION) (PTY) LTDInventors: Geoffrey John DAVIES, Mosimanegape Stephen Masete

Publication number: 20110259642Abstract: Cutting elements, earth-boring drill bits having such cutting elements and related methods are described herein. In some embodiments, a cutting element for an earth-boring tool may include a diamond table having an indentation in a cutting face thereof and a shaped feature in a substrate at the interface between the diamond table and the substrate, the shaped feature corresponding to the indentation in the cutting face of the diamond table. In further embodiments, a cutting element for an earth-boring tool may include a sacrificial structure positioned within an indentation in a diamond table. In additional embodiments, a method of forming a cutting element may include positioning a sacrificial structure in a mold, positioning a powdered precursor material over the sacrificial structure, and pressing and sintering the powdered precursor material to form a diamond table having an indentation in a cutting face formed by the sacrificial structure.Type: ApplicationFiled: April 22, 2011Publication date: October 27, 2011Applicants: ELEMENT SIX (PRODUCTION) (PTY) LTD., BAKER HUGHES INCORPORATEDInventors: Anthony A.

Publication number: 20110088950Abstract: Cutting elements for earth-boring tools may generate a shear lip at a wear scar thereon during cutting. A diamond table may exhibit a relatively high wear resistance, and an edge of the diamond table may be chamfered, the combination of which may result in the formation of a shear lip. Cutting elements may comprise multi-layer diamond tables that result in the formation of a shear lip during cutting. Earth-boring tools include such cutting elements. Methods of forming cutting elements may include selectively designing and configuring the cutting elements to form a shear lip. Methods of cutting a formation using an earth-boring tool include cutting the formation with a cutting element on the tool, and generating a shear lip at a wear scar on the cutting element. The cutting element may be configured such that the shear lip comprises diamond material of the cutting element.Type: ApplicationFiled: October 1, 2010Publication date: April 21, 2011Applicants: BAKER HUGHES INCORPORATED, ELEMENT SIX (PRODUCTION) (PTY) LTD.Inventors: Danny E. Scott, Marcus R. Skeem, Jeffrey B. Lund, John H. Liversage, Moosa Mahomed Adia

Publication number: 20110073379Abstract: A cutting element comprising a substrate having an upper surface, a rear surface spaced apart from the upper surface, and a side surface connected to the rear surface and upper surface. The cutting element further includes a superabrasive layer comprising a rear surface, an upper surface, and a side surface connected to and extending between the rear surface and upper surface, wherein the rear surface of the superabrasive layer overlies the upper surface of the substrate. The cutting element is also formed to include a jacket overlying the side surface of the substrate and abutting a portion of the rear surface of the superabrasive layer, wherein the jacket comprises a flange extending along a portion of the side surface of the superabrasive layer.Type: ApplicationFiled: September 24, 2010Publication date: March 31, 2011Applicants: BAKER HUGHES INCORPORATED, ELEMENT SIX (PRODUCTION) (PTY) LTD, ELEMENT SIX LIMITEDInventors: Anthony A.
