Abstract

Abstract: The anodic passivation behaviors of iron and nickel in sulfuric acid solution under the influence of magnetic field have been studied. The increase of passivation current density and the positive shift of passivation potential with the enhancement of magnetic field can be attributed to magneto-hydrodynamic effect and iRchange of solution respectively. The mechanism of passivation is discussed.

Key words: Anodic passivation, Passivations current densition, Passivation, potential, Magnetic flux:density
