Abstract

The effects of magnetocorrosion, altered corrosion behavior in the presence of magnetic fields, are described for pipeline steels. Changes in corrosion behavior, including pitting, cracking, and hydrogen ingress, were assessed with and without an applied magnetic field. Electrochemical charging of pipeline steel specimens in the presence of a magnetic field led to significant increases in observed magnetocorrosion. Correlation of the observed corrosion with microstructure, mechanical properties, and magnetic properties was utilized to determine the important factors in magnetocorrosion. Electrochemical impedance spectroscopy testing indicated a significant impedance shift in the presence of a magnetic field.
