Abstract: Nickel is a ferromagnetic material. These materials have some unpaired electrons, so their atoms have a net magnetic moment. They get their strong magnetic properties due to the presence of magnetic domains. Electrodeposited Ni has been used in Integrated circuits, service apparatus and functionally suitable metal coating. In this study, Ni is potentiostatically electrodeposited both in presence (sonication) and absence (silent) of ultrasound. The use of ultrasound irradiation during the deposition generates a specific agitation resulting from the cavitation phenomena and can possibly alter the mechanism and kinetics of phase formation. Crystalline graphite substrate is chosen for the study because of the lower nucleation rate on carbon compared with metallic electrodes. Thus the overlap of the nuclei can be delayed and hence the morphology of the nuclei can be fairly distinct. The conventional Watt’s bath is chosen for the electroplating, with a modification in the deposition tempera...
