Magnetic field exposure on electroplating process of ferromagnetic nickel ion on copper substrate

In this research, nickel electroplating was carried out under a magnetic field. A constant magnetic field was used to influence the electroplating process. Its effects on surface morphology, deposition rate, current efficiency, crystal structure, hardness, and corrosion properties of nickel films were investigated. Inhomogeneous pyramidal-type structures without crevices were formed on all samples. Ni films electrodeposited under exposure of 0.14T of the magnetic field revealed the highest deposition rate, current efficiency, and hardness. Less crystallite size would produce higher hardness. Three major peaks of X-ray diffraction are observed, and the (111) crystal plane is the most affected by the magnetic field during the electroplating process. The presence of 0.14T of magnetic field on the electrodeposition process also decreases (111) plane, crystallite size, and microstrain. A magnetic field could improve the corrosion and hardness properties of Ni films.
