【 摘 要 】

The aim of this work is to overview effects of a homogeneous magnetic field on the nucleation and growth crystal in electrodeposition processes, according to its amplitude and orientation with respect to the substrate. In this presentation, examination of such interest is given after a brief resume of a model that is generally used to describe the current transients corresponding to the early stages of nucleation and growth. Magnetic field superimposition during electrodeposition generates magnetohydrodynamic (MHD) convection and micro-MHD effect that interact on nucleation and growth phenomena from the very first moment of deposit.
