Special Issue Information

Dear colleagues,

We would like to invite you to submit your works to a Special Issue on “Electrochemically and Electrophoretically Deposited Thin Films and their Applications”. A thin film is a layer of material with thickness ranging from fractions of a nanometer to several micrometers. Thin films play an important role in the development and study of materials with new and unique properties. Advances in thin-film deposition techniques have enabled a wide range of technological breakthroughs in many industrial areas. Among the known methods for producing thin-film coatings, the methods of electrochemical and electrophoretic deposition (EPD and ELD) are distinguished by their flexibility of application, the possibility of applying various materials on a complex surface, the low cost of equipment, the ability to obtain films of a given thickness by controlling the deposition parameters and the short timeframe required. The scope of these deposition methods differs significantly – from electrochemical devices, such as fuel cells, batteries, supercapacitors, various sensors and MEMS devices, to thermal protective, hardening and decorative coatings, and even biomolecules, such as enzymes and proteins.

For this Special Issue, we are inviting you to present original papers or reviews on the latest experimental and theoretical developments in the field of electrochemical and electrophoretic deposition of thin-film coatings. Topics of interest for this Special Issue include, but are not limited to the following:

  • Latest theoretical and experimental studies in the field of the formation of thin-film structures by ELD and EPD for energy storage and generation devices
  • Application of ELD and EPD in additive technologies
  • ELD and EPD for the formation of multifunctional organic and inorganic, hybrid, nanostructured coatings using nanoparticles, carbon nanotubes, graphene, polymers, metals, alloys
  • ELD and co-deposition (combined with EPD or other methods) of metal and composite protective coatings
  • Deposition in modulated electric fields
  • New methods of characterization of EPD and ELD thin-film structures.
  • Methods of computer simulation of the processes of formation of thin films and methods for predicting their properties.
  • Novel experimental setups for ELD and EPD

The investigation of Fe-W alloys is growing in comparison to other W alloys with iron group metals due to the environmental and health issues linked to Ni and Co materials. The influence of Na2WO4 concentration in the range 0 to 0.5 M on bath chemistry and electrode reactions on Pt in Fe-W alloys’ electrodeposition from citrate electrolyte was investigated by means of rotating disk electrode (RDE) and cyclic voltammetry (CV) synchronized with electrochemical quartz crystal microbalance (EQCM). Depending on species distribution, the formation of Fe-W alloys becomes thermodynamically possible at potentials less than −0.87 V to −0.82 V (vs. Ag/AgCl). The decrease in electrode mass during cathodic current pass in the course of CV recording was detected by EQCM and explained. The overall electrode process involving Fe-W alloy formation may be described using formalities of mixed kinetics. The apparent values of kinetic and diffusion currents linearly depend on the concentration of Na2WO4. Based on the values of partial currents for Fe and W, it was concluded that codeposition of Fe-W alloy is occurring due to an autocatalytic reaction, likely via the formation of mixed adsorbed species containing Fe and W compounds or nucleation clusters containing both metals on the electrode surface.

Abstract
In this work, the challenges associated with the formation of single and bilayer coatings based on Ce0.8Sm0.2O1.9 (SDC) and CuO modified BaCe0.5Zr0.3Y0.1Yb0.1O3−δ (BCZYYbO-CuO) solid state electrolytes on porous non-conducting [...] Read more.
In this work, the challenges associated with the formation of single and bilayer coatings based on Ce0.8Sm0.2O1.9 (SDC) and CuO modified BaCe0.5Zr0.3Y0.1Yb0.1O3−δ (BCZYYbO-CuO) solid state electrolytes on porous non-conducting NiO-SDC anode substrates by the method of electrophoretic deposition (EPD) are considered. Various approaches that had been selected after analysis of the literature data in order to carry out the EPD, are tested: direct deposition on a porous non-conductive anode substrate and multiple options for creating the conductivity of the anode substrate under EPD conditions such as the reduction of the NiO-SDC substrate and the creation of a surface conducting sublayer via synthesizing a polypyrrole (PPy) film. New effective method was proposed based on the deposition of a platinum layer on the front side of the substrate. It was ascertained that, during the direct EPD on the porous NiO-SDC substrate, the formation of a continuous coating did not occur, which may be due to insufficient porosity of the substrate used. It was shown that the use of reduced substrates leads to cracking and, in some cases, to the destruction of the entire SDC/NiO-SDC structure. The dependence of the electrolyte film sinterability on the substrate shrinkage was studied. In contrast to the literature data, the use of the substrates with a reduced pre-sintering temperature had no pronounced effect on the densification of the SDC electrolyte film. It was revealed that complete sintering of the SDC electrolyte layer with the formation of a developed grain structure is possible at a temperature of 1550 °C. Full article
