Abstract: An article comprising a turbine component formed of a nickel-chromium (Ni—Cr) alloy including from 2 to 50 wt % chromium balanced by nickel is disclosed. The Ni—Cr alloy is thicker than at least 125 μm to make a self-supporting turbine component, and the turbine component includes a rotor blade, a stator, or a vane. The Ni—Cr alloy is electroformed on a mandrel by providing an external supply of current to an anode and a cathode in a plating bath containing a solvent, a surfactant, and an ionic liquid including choline chloride, nickel chloride, and chromium chloride.
