Nickel Electrodeposition under Influence of Constant Homogeneous and High-Gradient Magnetic Field

The paper is devoted to a study on nickel electrodeposition under an external applied constant magnetic field. The deposit structure was compared for the three different models: electrodeposition without the magnetic field application, that in a constant homogeneous magnetic field up to 5 kOe, and that in a constant hi-gradient magnetic field. The arborous dendritic structure was obtained under influence of a gradient magnetic field while the smooth structures were observed in a homogeneous magnetic field as well as for electrodeposition without magnetic field application. Influence of a gradient magnetic force on microstructure of the deposits is discussed.
