Abstract: A roller cone drill bit having a layer of wear resistant material applied thereon utilizing a thermal spray process and methods of manufacturing such drill bits.

Abstract: A hardfacing composition comprising an iron-based binder alloy; and a carbide phase comprising a sintered carbide and a cast tungsten carbide, wherein the cast carbide is present in a quantity of at least 22% by weight, based on the total weight of the carbide phase, and the cast carbide comprises particles having sizes in the range of from 30 to 60 mesh. Also provided is a hardfacing composition comprising an iron-based binder alloy; and a carbide phase comprising a super dense sintered carbide and one or more additional carbide materials, wherein the super dense sintered carbide is present in a quantity of at least 10 percent by weight (% w), based on the total weight of the carbide phase, and comprises particles having sizes in the range of from 16 to 40 mesh. Included are methods of manufacturing such hardfacing compositions and downhole tools having such improved hardfacing compositions applied thereon.

Abstract: A carbide composite material that includes a continuous ductile phase; and at least one discrete carbide region surrounded by the continuous ductile phase, each discrete carbide region may comprise an integrally bridged plurality of cast and/or sintered carbide particles, and each discrete region may have a nodular particle morphology.

Abstract: A conductor cleaning system for cleaning aluminum strands of all aluminum and steel reinforced conductors, such as ACSS, ACSR, ACAR, and AAA. The conductor cleaning system having a container adapted to receive a portion of a conductor to be cleaned, a housing adapted to receive and support the container, and a cleaning solution contained in the container for cleaning the portion of the conductor. The cleaning solution being adapted to clean the conductor without reacting with or damaging the conductor.
