  • Additive manufacturing of iron-based amorphous metal alloys
    Patent number: 11427902
    Abstract: Embodiments disclosed herein relate to production of amorphous alloys having compositions of iron, chromium, molybdenum, carbon and boron for usage in additive manufacturing, such as in layer-by-layer deposition to produce multi-functional parts. Such parts demonstrate ultra-high strength without sacrificing toughness and also maintain the amorphous structure of the materials during and after manufacturing processes. An Amorphous alloy composition has a formula Fe100-(a+b+c+d)CraMobCcBd, wherein a, b, c and d represent an atomic percentage, wherein: a is in the range of 10 at. % to 35 at. %; b is in the range of 10 at. % to 20 at. %; c is in the range of 2 at. % to 5 at. %; and d is in the range of 0.5% at. % to 3.5 at. %.

  • System and method for applying amorphous metal coatings on surfaces for the reduction of friction
    Patent number: 11078560
    Abstract: An embodiment relates to a composition comprising an amorphous alloy having a low coefficient of friction (COF) of 0.15 or less, wherein the amorphous alloy is substantially free of phosphor (P) and substantially free of boron (B). An embodiment relates to a method comprising solidifying a molten layer of an amorphous feedstock on a preexisting layer by controlling a heating source and a cooling rate so as to avoid formation of crystals in the molten layer and not affect a crystalline structure of the preexisting layer, and forming a specimen; wherein, the at least a portion specimen has the low COF. Another embodiment relates to a system comprising a drill string, wherein the drill string comprises a drilling bit and a drill pipe connected thereto, wherein at least a portion of the drill pipe comprises a coating having the low COF.
