    摘要： A method for producing a titanium foil according to the present invention includes an electrodeposition step of performing electrolysis with electrodes including an anode and a cathode using a molten salt bath comprising titanium ions and having at least one molten chloride to deposit metal titanium onto an electrolytic surface of the cathode, wherein the electrodeposition step includes maintaining a ratio of a molar concentration of titanium ions to the total molar concentration of metal ions in the molten salt bath at 7% or more, and maintaining a temperature of the molten salt bath at 510° C. or less, and conducting a current to the electrodes under conditions where a continuous stop time of current conduction is less than 1.0 second, a current density is 0.10 A/cm2 or more and 1.0 A/cm2 or less, and a time for electrodepositing the metal titanium onto the electrolytic surface of the cathode is 120 minutes or less.

    摘要： Provided herein is a composition for forming a metal deposit on a substrate. The composition consists essentially of a carboxamide, trialkylamine chloride, and a metal salt. The carboxamide comprises Formula (I). The trialkylamine chloride and the carboxamide are in molar ratio between 1:1 and 1:30 to form an ionic liquid. The trialkylamine chloride is trimethylamine chloride (TMACl), triethylamine chloride (TEACl), triethanolamine chloride, or combinations thereof. The metal salt has the formula MXy, wherein M is a metal, X is a halide, and y is an oxidation number of M, the metal salt being in a concentration between about 0.2 and about 1.5 moles per liter of the ionic liquid. The metal deposit has an average grain size between about 0.2 μm and about 3 μm and contains less than about 1 mol % of each oxygen, carbon, and chlorine.

    摘要： An electrochemical system includes at least one electrochemical cell with a receptacle containing an electrolytic bath in which is disposed a counter electrode. At least one nozzle opens from the receptacle toward and proximate a substrate configured as a working electrode. The at least one electrochemical cell is selectively configurable between a configuration for electrodeposition of a material onto the substrate and a configuration for electrodissolution of material from a structure on the substrate. In a method of using an electrochemical cell, a metal salt—of the electrolytic bath—is flowed through the nozzle in the presence of at least one of a voltage difference and a current flow between the working electrode and the counter electrode. The system may be configured for relative movement between the at least one nozzle and the substrate, and the electrochemical cell(s) may be usable for any of electrodeposition, electrodissolution, and electrochemical sensing.

    摘要： An electrochemical deposition system—for the electrochemical deposition of a metal-based material (e.g., aluminum or an aluminum alloy)—comprises an electrolyte solution, at least one working electrode, and at least one counter electrode. The electrolyte solution comprises at least one imidazolium-based tetrahalo-metallate compound (e.g., alkyl methylimidazolium tetrachloroaluminate(s)) and at least one metal-containing compound (e.g., AlCl3, AlBr3) of a metal of the metal-based material to be electrodeposited on the at least one working electrode. The working electrode is configured to be exposed to the electrolyte solution. The at least one counter electrode is in contact with the electrolyte solution. In some embodiments, the system is configured for additive manufacturing of the metal-based material being electrochemically deposited. Related methods are also disclosed.
