Nickel layers properties produced by electroplating were influenced by spinning permanent magnet

Abstract

A spinning magnet is an alternative engineering approach to produce the Ni layer. In the present research, the Ni layer was plated on Cu alloy substrates influenced by a spinning magnet. Various rotating speeds (0, 500, and 800 rpm) were used to influence the Ni layer’s properties were formed. A digital scale was used to measure the deposition rate and cathodic current efficiency. XRD, SEM-EDS, potentiostat, and hardness tests were performed to determine the properties of the Ni layers. A rotating magnetic field can reduce the deposition rate and cathodic current efficiency by reducing the ionic movement from the anode to the cathode. The XRD and SEM results revealed a distinct crystallite size and surface morphology. Exhibiting a spinning could result in a decrease in oxygen in the Ni layer and a slight change in the corrosion rates. Different hardness is also seen in the various sample due to crystallite size.
