In one aspect of the present invention, a high impact resistant tool, having a super hard material is bonded to a cemented metal carbide substrate at a non-planar interface. The cemented metal carbide substrate is bonded to a front end of a cemented metal carbide segment. A stem is formed in the base end of the carbide segment opposite the front end and the carbide stem is press fitted into bore of a steel body.

摘要:
A high-impact resistant pick having a superhard material bonded to a cemented metal carbide substrate at a non-planar interface. The cemented metal carbide substrate is bonded to a front end of a cemented metal carbide bolster. A bore formed in a base end of the carbide bolster is generally opposed to the front end. A steel body has a shaft extending distally from a shelf, and which shaft is fitted into the bore of the bolster at an interface. A shank adapted for connection to a driving mechanism extends proximally from the steel body opposite the shaft. A washer is disposed intermediate the base end of the carbide bolster and the shelf of the steel body.

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.
