    Abstract: Earth-boring tools such as, for example, earth-boring rotary drill bits include erosion-resistant structures disposed proximate areas of intersection between faces of the tools and fluid nozzle recesses or fluid passageways extending through the tools to the face. In some embodiments, such an erosion-resistant structure may comprise a mass of hardfacing material. In additional embodiments, such an erosion-resistant structure comprises an erosion-resistant insert. Methods of forming such earth-boring tools include providing erosion-resistant structures proximate intersections between the faces of the tools and fluid nozzle recesses or fluid passageways extending through the tools. Methods of repairing earth-boring tools include providing an annular-shaped, erosion-resistant structure over an eroded surface of a body of a previously used earth-boring tool proximate an intersection between an outer face of the body and an inner surface of the body.

    Abstract: Se aplica revestimiento duro en la superficie patrón de las cuchillas de la barrena, los filos delantero y trasero de las cuchillas de la barrena, y en las inserciones de carburo. La superficie patrón contiene diamantes naturales, diamantes sintéticos, diamantes policristalinos térmicamente estables (TSP) e inserciones de carburo, y el revestimiento duro se aplica sobre por lo menos una porción de los mismos. Cuando las cortadoras primarias en las cuchillas de la barrena se desgastan durante la perforación, la superficie patrón de la barrena también se desgasta. Se aplica un revestimiento duro en las superficies patrón desgastadas de la barrena, permitiendo que la barrena perfore más profundo y abarque una mayor distancia sin requerir reemplazo.

    Abstract: The present invention relates to a system and method for automated or "robotic" application of hardfacing to the surface of a steel-toothed cutter of a standard earth-boring rock bit or a hybrid-type rock bit. In particular, the system incorporates a grounded adapter plate and chuck mounted to a robotic arm for grasping and manipulating a rock bit cutter beneath an electrical or photonic energy welding source, such as a plasma arc welding torch manipulated by a positioner. In this configuration, the torch is positioned substantially vertically and oscillated along a horizontal axis as the cutter is manipulated relative along a target path for the distribution of hardfacing. Moving the cutter beneath the torch allows more areas of more teeth to be overlayed, and allows superior placement for operational feedback, such as automatic positioning and parameter correction. In the preferred embodiment, sensors provide data to the control system for identification, positioning, welding program selection, and welding program correction. The control system, aided by data from the sensors, manipulates the robotically held cutter while controlling the operation and oscillation of the torch. These systems and methods can be applied to hardfacing steel teeth of the rolling cutters of both standard tri-cone or di-cone type rolling cone bits, as well as to hybrid-type earth boring drill bits.

    Abstract: Earth-boring tools include at least one up-drill feature disposed on a transition surface so as to be passive during down drilling and active during up drilling and/or back reaming operations. Systems for down drilling and up drilling with drill bits comprising one or more up-drill features are also disclosed. Furthermore, methods for forming a borehole with an earth-boring tool including such up-drill features and for forming an earth-boring tool comprising such up-drill features are also disclosed.
