A magnetic field induced undulated surface and the shift of the active/passivation transition threshold of iron in a sulfuric acid solution
Source abstract
Abstract
Abstract An unevenly distributed magnetic field caused irreversible electrochemical states of iron in a sulfuric acid solution due to the undulated surface generated by anodic dissolution. The magnetic field affected the activation-passivation transition threshold by modifying the interface reaction rate and surface morphology. The passivation onset potential was increased by decreasing the scan rate under 0.4 T, and was insensitive to the scan rate at 0 T.
