    Abstract: The present disclosure relates to a cold spray metal process for providing an electrical connection within a multilayered composite article. The present disclosure relates to a cold sprayed metal coated article or a structural component having a polymeric composite material having at least one surface, a thermoplastic electrochemical insulating layer on the at least one surface, an electrical circuit may include a cold sprayed metal coating present on at least a portion of a surface of the electrochemical insulating layer, and at least one additional layer, the at least one additional layer encapsulating at least a portion of the cold sprayed metal between the additional layer and the electrochemical insulating layer. The structural component may include a cold sprayed metal coating having one or more non-continuous segments, where the one or more non-continuous segments are not in lateral contact with one another.

    Abstract: Electrolyte solutions for electrodeposition of zinc alloys and methods of electrodepositing zinc-iron alloys. An electrolyte solution for electroplating can include an alkali metal hydroxide, a zinc salt, a condensation polymer of epichlorohydrin, a quaternary amine, an aliphatic amine, a polyhydroxy alcohol, an aromatic organic acid and/or salts thereof, an amino alcohol, a bisphosphonic acid and/or salts thereof, an iron salt, an alkali metal gluconate, and an amine-based chelating agent. Electrodepositing zinc alloys on a substrate can include introducing a cathode and an anode into an electrolyte solution comprising an alkali metal hydroxide, a zinc salt, a condensation polymer of epichlorohydrin, a quaternary amine, an aliphatic amine, a polyhydroxy alcohol, an aromatic organic acid and/or salts thereof, an amino alcohol, a bisphosphonic acid and/or salts thereof, an iron salt, an alkali metal gluconate, and an amine-based chelating agent.

    Abstract: The present disclosure provides compositions, articles thereof, and methods of forming compositions. In at least one aspect, a composition includes (1) an epoxy, (2) an amino or amido hardener, (3) a polyaniline, (4) a dopant selected from a triazolyl, a thiazolyl, a quinolinyl, a salicylate, a benzoate, a glycolate, a phosphate, a sulfonate, or combination(s) thereof; and (5) a pigment selected from titanium dioxide, silica, talc, mica, aluminium stearate, or combination(s) thereof. The polyaniline+dopant comprises 6 wt % or less, by total volume of the composition. The present disclosure provides substrates having a composition disposed thereon. In at least one aspect, a method includes introducing an acid form of a polyaniline to a hydroxide to form a polyaniline hydroxide. The method includes introducing a dopant to the polyaniline hydroxide to form a doped polyaniline.

    Abstract: An electrolyte solution for iron-tungsten plating is prepared by dissolving in an aqueous medium a divalent iron salt (e.g., iron (II) sulfate) and an alkali metal citrate (e.g., sodium citrate, potassium citrate, or other alkali metal citrate) to form a first solution, dissolving in the first solution a tungstate salt (e.g., sodium tungstate, potassium tungstate, or other potassium tungstate) to form a second solution, and dissolving in the second solution a citric acid to form the electrolyte solution. An iron-tungsten coating is formed on a substrate using the electrolyte solution by passing a current between a cathode and an anode through the electrolyte solution to deposit iron and tungsten on the substrate.
