Electrodeposition of NiFe Alloys in a Magnetic Field

The effects induced by a static magnetic field that was superimposed during the electrodeposition of NiFe alloy were investigated. It was found that the iron content of the alloy, the partial current due to hydrogen evolution reaction, the morphology and the texture of the alloys change when the magnetic field is applied perpendicular to the electric field lines. Beside changes in the morphology on a microscopic scale, no other significant effects were obtained when the magnetic field lines and the electric field lines were parallel to each other. The effects observed were considered to be induced by the additional convection generated by the interaction between the MHD convection and the natural convection.
