Abstract
It has been demonstrated that the deposit quality of nickel electroforms can be enhanced by using a magnetic field. Less research work has been carried out to examine the effect of magnetic fields on the surface finish of nickel electroforms using a nickel sulphamate bath and low magnetic flux densities. In this paper, it has been found that the surface finish of nickel electroforms can be improved by applying a magnetic field. The best surface finish is obtained at a magnetic field of 5 mT and at a current density of 8 A dm-2. A change in the intensity of the (200) peak is observed in the nickel electroforms under different magnetic flux densities. In this paper, the effect of a magnetic field on surface finish has been examined theoretically. It is believed that the presence of a magnetic field may increase the diffusion layer thickness and hence improve the surface finish.
