Abstract

Metal corrosion causes significant financial burden to engineering infrastructure management agencies. Effective monitoring of corrosion enables appropriate maintenance action and results in cost savings. In this paper a novel magnetic sensing approach to monitor corrosion, which overcomes some difficulties faced by traditional NDE techniques for corrosion, is described. In the method a focused magnetic field is imposed on a metal surface, and the resulting secondary field from the interaction with the metal is monitored remotely with GMR magnetic field sensors. Obtained magnetic field data are presented for metal under different corrosion conditions (active and passive). The effects of corrosion condition, sensor distance and angle are discussed and pertinent behaviors are discussed.
