Electrodeposition of Fe-Zn, Fe-Mn and Fe-Zn-Mn alloys on steel from ionic liquids

Ionic liquids containing solely anions and cations (without solvent) have been employed as metals and alloys electrodeposition baths. Growth conditions have a considerable impact on the surface properties of coatings. In this study, electrodes composed of Fe alloys such as Fe-Zn, Fe-Mn, and Fe-Zn-Mn were produced on the surface of steel using an ionic liquid solution. Thin film coatings with nanostructures were obtained uniformly on the steel surface. A scanning electron microscope, an energy dispersive spectrometer, X-Ray Diffraction and a Fourier Transform Infrared Spectrometer were used to characterize the surface morphologies, compositions, and structures of the synthesized coatings. The corrosion behavior of the alloy coatings was determined by linear sweep voltammetry.
