Definitions
- Embodiments of the present disclosure generally relate to methods of forming spherical titanium-based metallic particles. More particularly, embodiments of the present disclosure relate to methods of forming spherical titanium alloy particles using microwave plasma.
- Spherical powders are homogenous in shape, dense, less porous, and exhibit better flowability. Such powders may exhibit superior properties in applications such as injection molding, thermal spray coatings, or additive manufacturing.
- Titanium and titanium-alloy particles are particularly useful in additive manufacturing of industrial grade components. Additive manufacturing of titanium components may require high-quality, low-cost spherical titanium or titanium alloy powder as a feedstock for good flowability.
- Conventional methods for processing of titanium alloys to produce spherical powders typically involve multiple steps, such as, producing titanium ingots from sponges and utilizing melting and atomization processes on the titanium ingots to produce spherical powder.
- the formation of titanium powder can be facilitated by one of several approaches, such as, the Kroll process, the Hunter process, or the Armstrong process.
- most of these commercial processes are typically carried out as large-scale processes and are batch segregated, which increases the complexity and associated cost.
- the intermediate metallurgical processes for conversion to alloys may add to the cost of the resulting spherical titanium alloy powder.

- Approximating language may be applied to modify any quantitative representation that could permissibly vary without resulting in a change in the basic function to which it is related. Accordingly, a value solidified by a term or terms, such as“about”, and“substantially” is not to be limited to the precise value specified. In some instances, the approximating language may correspond to the precision of an instrument for measuring the value. Similarly,“free” may be used in combination with a term, and may include an insubstantial number, or trace amounts, while still being considered free of the solidified term.
- range limitations may be combined and/or interchanged, such ranges are identified and include all the sub-ranges contained therein unless context or language indicates otherwise.
- a method of forming spherical metallic particles including titanium includes performing a hydride-dehydride process on a meltless metallic sponge to form a feedstock material including a metallic powder.
- the feedstock material is introduced into a microwave plasma discharge to form the spherical metallic particles.
- the term“metallic particles” as used herein refers to a plurality of particles including an elemental metal, a metal alloy, or a combination thereof. Therefore, the term metallic particles as used herein includes elemental titanium, a titanium-based metal alloy, or a combination thereof.
- the term“elemental metal” as used herein means that an amount of a base metal in the metallic particles is greater than 97 weight percent. In certain embodiments, an amount of the base metal in the metallic particles is greater than 99 weight percent. Therefore, the term“elemental titanium” as used herein means than an amount of titanium in the metallic particles is greater than 97 weight percent.

- the metal alloy may further include aluminum, vanadium, or a combination thereof.
- the spherical metallic particles include titanium alloy particles, such as, T ⁇ 6A14U.

- meltless metallic sponge refers to a metallic material present in the form of a sponge that has been produced without melting of the metallic material.
- the meltless metallic sponge may be produced by chemically reducing suitable precursors for the metallic material, without melting the metallic material.
- “without melting,” “no melting,” and related concepts mean that the material is not macroscopically or grossly melted, so that it liquefies and loses its shape. There may be, for example, some minor amount of localized melting as low-melting-point elements melt and are diffusionally alloyed with the higher-melting-point elements that do not melt. Even in such cases, the gross shape of the material remains unchanged.
- the Hunter Process or the Armstrong Process may be used to form the meltless metallic sponge by reduction of metal halide precursors with sodium.
- the Kroll Process may be used to produce the meltless metallic sponge by reducing titanium tetrachloride with magnesium.
- the method of forming a meltless metallic sponge of a metal alloy includes contacting a chemically reducible nonmetallic base-metal precursor compound with a chemically reducible nonmetallic alloying-element precursor compound.
- “Nonmetallic precursor compounds” are nonmetallic compounds of the metals that eventually constitute the metal alloy. Any operable nonmetallic precursor compounds may be used. For example, oxides of the metals may be employed as nonmetallic precursor compounds in solid-phase reduction, but other types of nonmetallic compounds such as sulfides, carbides, halides, and nitrides may also be employed.
- The“base-metal” is a metal that is present in a greater percentage by weight than any other element in the metal alloy.
- the base-metal is titanium
- the chemically reducible nonmetallic base- metal precursor compound includes titanium oxide, TiC .
- the alloying element may be any element that is available in the chemically reducible form of the precursor compound. A few illustrative examples are aluminum and vanadium.
- the chemically reducible nonmetallic precursor compounds are selected to provide the desired metals in the final meltless metallic sponge, and are mixed together in the proper proportions to yield the desired proportions of these metals in the meltless metallic sponge.
- the chemically reducible nonmetallic precursor compounds may include titanium oxide, aluminum oxide, and vanadium oxide, for solid- phase reduction in the particular proportions.
- Chemically reducible nonmetallic precursor compounds that serve as a source of more than one of the metals in the final meltless metallic sponge may also be used.
- the final meltless metallic sponge includes a titanium-base alloy, which has more titanium by weight than any other element.
- the chemically reducible nonmetallic base-metal precursor compound and the chemically reducible nonmetallic alloying-element precursor compound may be in the form of finely divided solids to ensure that they are chemically reacted in the subsequent step.
- the finely divided chemically reducible nonmetallic base-metal precursor compound and the chemically reducible nonmetallic alloying-element precursor compound may be in the form of, for example, powders, granules, flakes, liquids, or the like.
- the chemically reducible nonmetallic base-metal precursor compound and the chemically reducible nonmetallic alloying-element precursor compound may be mixed to form a compound mixture.
- the mixing may be performed by conventional procedures used to mix powders in other applications, for solid-phase reduction.
- the compound mixture may be compacted to form a preform.
- the compacting may be conducted by cold or hot pressing of the compound mixture, but not at such a high temperature that there is any melting of the compound mixture.
- the compacted shape may be sintered in the solid-state to temporarily bind the particles together.
- the compacting desirably forms a shape similar to, but larger in dimensions than, the shape of the final meltless metallic sponge.
- the compacted compound mixture may be then reduced using solid-phase reduction.
- a non-limiting example of a suitable method to perform the solid-phase reduction includes fused salt electrolysis. Briefly, in fused salt electrolysis, the compound mixture is immersed in an electrolysis cell in a fused salt electrolyte, such as a chloride salt, at a temperature below the melting temperatures of the metals that form the compound mixture. The compound mixture is made the cathode of the electrolysis cell, with an inert anode. The oxygen, in the case of oxide nonmetallic precursor compounds, is removed from the mixture by chemical reduction (i.e., the reverse of chemical oxidation). The reaction is performed at an elevated temperature to accelerate the diffusion of the oxygen or other gases away from the cathode.
- a fused salt electrolyte such as a chloride salt
- the cathodic potential is controlled to ensure that the reduction of the nonmetallic precursor compounds occurs, rather than other possible chemical reactions such as the decomposition of the molten salt.
- the electrolyte is typically a salt that is more stable than the equivalent salt of the metals being refined and suitably stable to remove the oxygen.
- the chemical reduction may be carried to completion, so that the nonmetallic precursor compounds are completely reduced. In some other embodiments, the chemical reduction may instead be partial, such that some nonmetallic precursor compounds remain.
- the physical form of the metallic material at the completion of the solid-phase reduction process depends upon the physical form of the mixture of chemically reducible nonmetallic precursor compounds at the beginning of the solid-phase reduction process. As noted herein, as the mixture of chemically reducible nonmetallic precursor compounds is a compressed mass. Therefore, the final physical form of the metallic material is typically in the form of a porous metallic sponge.

- a similar method may be employed for forming a meltless metallic sponge composed primarily of an elemental metal.
