- W95457682 abstract "The present work is focused on the experimental and theoretical studies of the electrodeposition mechanism of Co-based films, including single Co, binary Co-Ni, Co-Cu and ternary Co-Ni-Cu alloy films. The modeling and structure-properties relationship by a multi-scale approach is investigated.The preliminary study involves determination and optimization of the electrodeposition parameters in order to obtain nanocrystalline films with satisfied surface quality and promising magnetic properties. It is shown that the electrolytic pH, to-be-deposited type of substrate and deposition time are of high importance in the fabrication of nanoscale materials. Among them, the electrolytic pH is the one, which has the greatest effect on the structure formation. The film growth as well as its quality can be strongly affected by a superimposition of an external magnetic field. The electrodeposition process was carried out under parallel to the electrode surface magnetic fields with magnets strength up to 12T. The results reveal that the induced forced convection in the electrolyte changes the hydrodynamic conditions and thus, affects the structure and morphology of the obtained films. Furthermore, the process kinetics and crystal growth are enhanced under magnetic electrodeposition conditions.Microstructure formed by the electrochemical processing is characterized by some significant magnetic properties, which may result in soft and/or hard magnetic materials, depending on their application approach. Additionally, the microstructure of films has been improved by the magnetic annealing treatment. Thus, the recrystallization and interdiffusion phenomena are observed, and modification of the magnetic properties is induced.Considering the electrodeposition process carried out in aqueous solutions the secondary process, which is the hydrogen evolution reaction (HER), needs to be taken into account. The theoretical study based on the tools of quantum mechanics (QM) and density functional theory (DFT) is used to determine the adsorption energies of hydrogen. In this work, the calculation results are related with the experimental study and may explain the structure formation assisted by the simultaneous evolution of hydrogen at the electrode surface." @default.
