Abstract: The present invention relates to an additive manufacturing system and its methods. The system includes a material conveyor, an energy source, and a micro-forging device. The material conveyor is configured to convey material. The energy source is configured to direct an energy beam toward the material, the energy beam fuses at least a portion of the material to form a solidified portion. The micro-forging device is movable along with the material conveyor for forging the solidified portion, wherein the micro-forging device comprises a first forging hammer and a second forging hammer, the first forging hammer is configured to impact the solidified portion to generate a first deformation, and the second forging hammer is configured to impact the solidified portion to generate a second deformation greater than the first deformation.

Abstract: A forging head for additive manufacturing, comprising a base portion and a forging portion. The forging portion extends from the base portion for forging a cladding layer during formation of the cladding layer by additive manufacturing. The forging head further comprising a through hole which is formed through the base portion and the forging portion, for at least one of an energy bean and an additive material to pass through during formation of the cladding layer.

Abstract: A fluid conduit (10) is provided having (a) a fluid conduit exterior surface (14); (b) a fluid conduit interior surface (16); (c) an electroless nickel protective coating (18) disposed upon one or both of the fluid conduit interior surface and the fluid conduit exterior surface; and (d) a layer (20) of Ni3S2 disposed upon and substantially covering the electroless nickel protective coating. The fluid conduit can be any fluid conduit through which a fluid may be caused to pass, such as a downhole tubular used in oil and gas production, or a gas liquid cyclonic separator. And a hydrocarbon production tube, a method of producing a fluid conduit comprising a nickel sulfide protective layer, a machine component comprising at least one surface having a protective outer layer are provided. The combination of the electroless nickel inner protective coating with an outer layer of Ni3S2 affords articles such as fluid conduits and machine components with exceptional scale and corrosion resistance.
