Abstract: The present disclosure is directed and formulations and methods to provide alloys having relative high strength and ductility. The alloys may be provided in seamless tubular form and characterized by their particular alloy chemistries and identifiable crystalline grain size morphology. The alloys are such that they include boride pinning phases. In what is termed a Class 1 Steel the alloys indicate tensile strengths of 700 MPa to 1400 MPa and elongations of 10-70%. Class 2 Steel indicates tensile strengths of 800 MPa to 1800 MPa and elongations of 5-65%. Class 3 Steel indicates tensile strengths of 1000 MPa to 2000 MPa and elongations of 0.5-15%.

Abstract: A method of applying a metallic alloy overlay including providing an iron based feedstock powder including 10 to 75 weight percent iron and manganese, 10 to 60 weight percent of chromium, 1 to 30 weight percent of an interstitial element selected from boron, carbon, silicon or combinations thereof, 0 to 40 weight percent of a transition metal selected from molybdenum, tungsten or combinations thereof and 1 to 25 weight percent niobium. The method also includes providing an electrode including at least 50 weight percent iron and depositing a weld overlay with the feedstock powder and the electrode to create a metallic alloy exhibiting a grain size in the range of 1,000 ?m or less.

Abstract: A drill pipe and a method of applying hardbanding thereto. A hardbanding alloy comprising iron and manganese present in the range of 67 to 87 weight percent (wt. %), niobium and chromium present in the range of 9 to 29 wt. %, and boron, carbon and silicon present in the range of 3 to 6.5 wt. % may be welded around at least a portion of a tool joint circumference. The hardbanding alloy may exhibit a hardness of 45 Rc to 70 Rc and a wear rate in the range of 0.08 grams to 1.60 grams of mass loss after 6,000 cycles as measured using ASTM G65-04, Procedure A.

Abstract: Thin coatings of normally solid materials are applied to target substrates using an inductively coupled plasma. Particles of the coating material are vaporized by plasma heating, and pass through an orifice to a first vacuum zone in which the particles are accelerated to a velocity greater than Mach 1. The shock wave generated in the first vacuum zone is intercepted by the tip of a skimmer cone that provides a second orifice. The particles pass through the second orifice into a second zone maintained at a higher vacuum and impinge on the target to form the coating. Ultrapure coatings can be formed.
