Appl. No.:

17/882525

Inventors:

- Lake Forest CA, US
Ricardo Salas - Lake Forest CA, US
Evelina Vogli - Lake Forest CA, US

International Classification:

C22C 45/02
B22F 1/05
B33Y 70/00

Abstract:

Embodiments disclosed herein relate to the production of amorphous metals 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. Two additive manufacturing techniques are provided: (1) the complete melting of amorphous powder and re-solidifying to amorphous structure to eliminate the formation of crystalline structure therein by controlling a heating source power and cooling rate without affecting previous deposited layers; and (2) partial melting of the outer surface of the amorphous powder, and solidifying powder particles with each-other without undergoing a complete melting stage. Amorphous alloy compositions have oxygen impurities in low concentration levels to optimize glass forming ability (GFA). Specific techniques of additive manufacturing include those based on lasers, electron beams and ultrasonic sources.

E21B 17/10

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.
