Abstract

Corrosion is a serious and costly problem for the world's infrastructure. Traditional non-destructive methods have proven to be useful in determining extent and rate of corrosion; however they are limited by the need to electrically connect to the inspected metal. Magnetic sensing is proposed as a way to overcome these limitations. Preliminary results are presented here on the use of GMR magnetic field sensors to passively and actively detect corrosion of aluminum and steel plates. Passive sensing seems particularly useful to identify localized active corrosion on aluminum, while active sensing appears useful to identify active corrosion in steel.
