摘要： A degradation assembly for use with a driving mechanism includes a working portion coupled to a shank assembly. The working portion has an impact tip brazed to a working end of a carbide extension. The carbide extension has a cavity formed in a base end that is adapted to engage with a shank and a locking mechanism of the shank assembly. The shank has an outer surface proximate a first end which is receivable within the cavity of the carbide extension. The locking mechanism has a radially extending catch configured to engage with the cavity and couple the shank assembly to the working portion. The shank has an outer surface proximate a second end which is adapted to be press-fitted within a recess of a driving mechanism.

摘要： In one aspect of the present invention, a degradation assembly comprises a pressing seal element and a pressurized rigid element disposed intermediate a rotating component and a stationary component. The rotating component comprising an impact tip bonded to an end opposing the stationary component. The seal element may energize the rigid element against one of the components to form a slidable seal capable of holding lubricant within the assembly and keeping debris out while still rotating.

摘要： In one aspect of the present invention a disc cutter for an earth boring system includes an axle and a sintered polycrystalline ceramic disc disposed about and forming a continuous perimeter around the axle. The disc cutter may be attached to a drill bit comprising a body, working face and plurality of blades.Another aspect of the present invention comprises a method of forming a disc cutter including providing a can of a generally cylindrical shape with a central axis, positioning a column of disposable material, carbide, and crystalline grains in such a manner so when put under high temperature and high pressure a compact in the shape of a disc cutter may be formed and a column from the center axis may be removed. Another method for forming a disc cutter comprises forming a plurality of compacts and bonding the compacts together in a generally toroidal shape.
