“…The deposition potential of less noble metals shifts through the interactions between components and the codeposition of cobalt and other metals becomes possible [53]. The situation is different in the case of an alloy with two ferromagnetic metals [51]. At a high potential, the amount of the more noble metal was lower in the alloy electrodeposited under magnetic field.…”

The paper presents and summarizes some research on constant magnetic field effects in chemistry. Metals and alloys electrodeposited under constant magnetic field have greater thickness and smoother surface with finest grains. Metallic materials deposited under the influence of uniform magnetic field may have stronger corrosion resistance, than those obtained without the presence of magnetic field. Constant magnetic field also causes an increase of the electropolymerization rate and yield of some organic reactions. Our research also shows that the presence of constant magnetic field affects the electrodeposition process of alloys and their morphology to a great extent. The effects of magnetic field on metals, alloys, composites, polymers and other materials are due to the Lorentz force and the magnetohydrodynamic effect. It is possible that the further development of magnetoelectrodeposition will allow for using the constant magnetic field to improve the properties of metal coatings, alloys, polymers, and other materials in the industry.

“…Using a quartz crystal microbalance, they confirmed the enhancement of the hydrogen current [11]. Koza and coworkers found that, during deposition of CoFe alloys, a field applied perpendicular to the electrode surface promotes hydrogen desorption, which they attributed to the twisting action of the Lorentz force around the growing hydrogen bubbles [12].…”

The codeposition of Ni-Co-Fe-Zn alloys from a mixture of 1-ethyl-3-methylimidazolium chloride (EMIC)/ethylene glycol (EG) was studied using potentiostatic electrodeposition in the potential range of -1.10 and -1.30 V vs saturated calomel electrode (SCE), using a permanent parallel magnetic field (PPMF) of 9 T. The uniform magnetic field was aligned parallel to the cathode surface. It was found that both normal and anomalous codeposition occurred. Films with different elemental percentage and deposit morphology were obtained from a mixture of EMIC/EG solution at the applied potentials (-1.10 and -1.30 V) in the absence and presence of a PPMF. The influence of magnetic field on the nucleation and growth process is studied with respect to the magneto-hydrodynamic effect (MHD) and applied potentials.
