“…When the magnetic field strength reaches a certain value (a few T to dozens T), it can even have an effect of Lorentz force and magnetic force on a very weak current and non-magnetic materials, thus largely expand its scope of application. Influence of magnetic field on material preparation process may performance in many ways: distribution of particles in composite coatings may be affected by the Lorentz force of the magnetic field, mass transfer process and crystal orientation may be affected by magnetizing force, in addition, chemistry reaction also may be affected to some extent by the magnetic field [19], [20]. Under acting of 10T-20T, even 100T super magnetic field, there are very significant influences on the chemical reaction system, and thus indirectly affect the performances of prepared materials.…”

Abstract. The research and development status of the electro-deposition technology under the action of external magnetic field are introduced. The basic characteristics and applied manners of external magnetic field in electrodeposition process are summarized. The acting principle of external magnetic field, the effects of magnetic hydrodynamics (MHD) caused by the Lorentz force, and the acting of magnetic force on the metal ions and particles are described. The main actions of external magnetic field include MHD effect, magnetizing force, affecting the physical and chemical properties of the bath, affecting the disperse ability and coverage capacity of bath, affecting the mass transfer process of electro-deposition, affecting the chemical reaction process and current distribution of electrode surface. Some examples of electro-depositing single metal coatings, alloy coatings and composite coatings under action of magnetic field are explained. During the electro-depositing process, the external magnetic field has different degrees of impact on solution properties, mass transfer, charge transfer, content of composited nanoparticles, crystal growth and crystal orientation etc. The specific impact of magnetic field during the electro-depositing is also classified and summarized. The problems that existed in electro-deposition process while applying magnetic field and the next development trend were summarized.

In this study, cobalt-nickel (Co-Ni) alloys were deposited electrochemically onto aluminum substrates under applied current densities of 103.8, 138.4, 173 and 207.6 A m −2 . Influence of the applied current density on the structural and magnetic properties of the Co-Ni alloys was investigated. The bath for Co-Ni alloys deposition was composed of 0.08 mol l −1 CoSO4·7H2O, 0.2 mol l −1 NiCl2·6H2O, 0.1 mol l −1 NiSO4·6H2O and 0.25 mol l −1 H3BO3. The electrochemical investigation of Co-Ni alloys was completed using cyclic voltammetry and galvanostatic studies. Inductively coupled plasma analysis has shown that the amount of the cobalt in the deposited alloy has decreased from 73.61% to 67.01% with the increase of the applied current density from 103.8 to 207.6 A m −2 . According to the magnetic analysis results, the values of coercivity coefficient of the deposited Co-Ni alloys range between 115 and 150 Oe, confirming ferromagnetic behavior of the alloys. Experiment results indicate that magnetic and structural properties of the Co-Ni alloy deposits are greatly influenced by the applied current density in the electrodeposition system.

“…Various methods can be used for the deposition of coatings, such as sputtering [8], vapor deposition [9], spin coating and electrodeposition [10][11][12]. Nonetheless, with the exception of electrodeposition, these methods are not effective for creation of coatings of high quality and well controlled magnetic layers [13].…”

Cobalt-Nickel alloys have been widely used for decoration, in magnetic recording devices and corrosion resistance applications, etc. In this study, the influences of cobalt amount in electrolyte on the magnetic and structural properties of the electrodeposited Co-Ni alloys were investigated. An electrolyte solution, consisting of cobalt sulfate, nickel sulfate, nickel chloride and boric acid, was used in electrodeposition. The electrochemical investigation of Co-Ni alloys was completed using cyclic voltammetry and galvanostatic studies. The morphological and structural analyses of the alloys were performed using inductively coupled plasma, scanning electron microscopy, X-ray diffraction and vibrating sample magnetometer techniques. The effect of cobalt concentration on the magnetic properties, phase structure and grain size of the alloys was investigated. Magnetic hysteresis results indicate that the amount of the cobalt content in the electrolyte has a strong influence on the ferromagnetic behavior of fabricated alloys. Results of the study show that changing the electrodeposition parameters, such as composition of electrolyte solution, allows to fabricate alloys with different properties.
