Abstract
The magnetic field distributions above the surface of in-situ active corroding 2024-T3 and 7075-T6 aircraft aluminum alloy plates have been measured using a high-resolution superconducting quantum interference device (SQUID) magnetometer. The magnetic field distributions and their variation with time are clearly different for the two aluminum alloys in an identical solution and for 2024-T3 in two different solutions. It is believed that these results demonstrate theability of SQUID to noninvasively detect in-situ active corrosion in aircraft aluminum alloys in a way that present corrosion-detection methods do not allow.
