Abstract
The effect of static magnetic field on atmospheric corrosion behavior of copper under thin electrolyte layer is investigated through polarization curves, electrochemical impedance spectroscopy, EDS and SEM techniques. The influences of the intensity and direction of magnetic field on the corrosion behavior are discussed. Results show that: mainly pitting corrosion occurs to the copper; the magnetic field reduces the ability of ions to migrate from thin electrolyte layer to electrode surface, and inhibits the formation of CuO and soluble copper chloride. The mechanisms involved are proposed to explain the inhibition effect.
