Abstract: A rotor catch system includes a catch stem having a proximal end coupled to a rotor of a mud motor system and a distal end positioned within a sub housing of a drill string, a catch feature having a top portion and a spindle portion extending from the top portion and coupled to the distal end of the catch stem, a housing catch feature extending radially inward from an inner surface of the sub housing, and a catch bushing positioned between the top portion of the catch feature and the housing catch feature. The housing catch feature restrains axial movement of the catch bushing in the active catch state via contact between the catch bushing and the housing catch feature, and the catch bushing restrains axial movement of the catch feature in the active catch state via contact between the catch feature and the catch bushing.

Abstract: A radial bearing for transmitting a radial load, including a first radial bearing component having an inner surface defining a bore and a second radial bearing component received within the bore of the first radial bearing component and having an outer surface. The first radial bearing component includes a plurality of first component wear resistant inserts arranged and mounted on the inner surface. The second radial bearing component includes a second component wear resistant coating on at least a portion of the outer surface. The first radial bearing component and the second radial bearing component interact to transmit the radial load between the first radial bearing component and the second radial bearing component.

Abstract: A wear resistant insert including a deposition substrate having an exterior surface, and a wear resistant layer deposited on the exterior surface of the deposition substrate. The wear resistant insert may further include a structure interface layer deposited on an exterior surface of the wear resistant layer. A method of forming a wear resistant insert including providing a deposition substrate having an exterior surface, and depositing a wear resistant layer on the exterior surface of the deposition substrate. The method may further include depositing a structure interface layer on an exterior surface of the wear resistant layer. The method may further include separating the wear resistant layer from the deposition substrate intact.

Abstract: Downhole tools such as bearing assemblies and stabilizers are described for withstanding abrasive and erosive wear in operation. These stabilizers and bearing assemblies employ wear-resistant hard materials such as TSP, PCD, leached WC, and SCD composite materials. A bond between a braze material and wear tiles constructed of a hard phase material may include a non-planar interface with the braze material. Self-lubricating materials may be provided within the braze material or the hard material in some instances.
