Abstract: The present disclosure provides electrolyte solutions for electrodeposition of zinc-manganese alloys, methods of forming electrolyte solutions, methods of electrodepositing zinc-manganese alloys, and multilayered zinc-manganese alloys. An electrolyte solution for electroplating can include a metal salt, boric acid, an alkali metal chloride, polyethylene glycol, and a hydroxy benzaldehyde. An electrolyte solution can be formed by dissolving a metal salt, boric acid, an alkali metal chloride, polyethylene glycol, and a hydroxy benzaldehyde in water or an aqueous solution. Electrodepositing zinc-manganese alloys on a substrate can include introducing a cathode and an anode into an electrolyte solution comprising a metal salt, boric acid, an alkali metal chloride, polyethylene glycol, and a hydroxy benzaldehyde. Electrodepositing can further include passing a current between the cathode and the anode through the electrolyte solution to deposit zinc and manganese onto the cathode.

Abstract: The present disclosure provides electrolyte solutions for electrodeposition of zinc-iron alloys, methods of forming electrolyte solutions, and methods of electrodepositing zinc-iron alloys. An electrolyte solution for electroplating can include an alkali metal citrate, an alkali metal acetate, a citric acid, and glycine with a metal salt. An electrolyte solution can be formed by dissolving an alkali metal citrate, an alkali metal acetate, a citric acid, and glycine in water or an aqueous solution. Electrodepositing zinc-iron alloys on a substrate can include introducing a cathode and an anode into an electrolyte solution comprising an alkali metal citrate, an alkali metal acetate, a citric acid, and glycine. Electrodepositing can further include passing a current between the cathode and the anode through the electrolyte solution to deposit zinc and iron onto the cathode.

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.
