摘要： An improved earth-boring bit the rolling cone variety and an insert for use therein is provided. A superabrasive element is coated with at least one layer of metallic material. The superabrasive element then is placed in a receptacle cavity in a pre-formed hard metal jacket. The superabrasive element then is brazed or infiltrated to the hard metal jacket. Metallurgical and mechanical bonds between the superabrasive element, the at least one layer of metallic material on superabrasive element, the braze or infiltrant binder material, and the fracture-tough material of the hard metal jacket retain the superabrasive element in the cavity of the hard metal jacket. Improved earth-boring bits according to this embodiment of the present invention provide abrasion-resistant earth-boring bits of the rolling cutter variety. Such improved bits, and the inserts therefore, are formed without resort to high-temperature, high-pressure processes.

摘要： Polycrystalline compacts include a hard polycrystalline material comprising first and second regions. The first region comprises a first plurality of grains of hard material having a first average grain size, and a second plurality of grains of hard material having a second average grain size smaller than the first average grain size. The first region comprises catalyst material disposed in interstitial spaces between inter-bonded grains of hard material. Such interstitial spaces between grains of the hard material in the second region are at least substantially free of catalyst material. In some embodiments, the first region comprises a plurality of nanograins of the hard material. Cutting elements and earth-boring tools include such polycrystalline compacts. Methods of forming such polycrystalline compacts include removing catalyst material from interstitial spaces within a second region of a polycrystalline compact without entirely removing catalyst material from interstitial spaces within a first region of the compact.
