A study of the effect of magnetic fields on the diffusion layer at the Fe/H2SO4 interface by holographic microphotography

Abstract

The effect of externally imposed magnetic fields on the relaxation of the concentration diffusion layer at the Fe/0.5 mol dm-3 H2SO4 interface after passivation of the iron electrode during potentiodynamic polarization was studied by holographic microphotography. The presence of a magnetic field was found to retard the relaxation process while the microturbulence was impeded.
