| Abstract: | With acceleratedly corroded samples and real corroded airframe parts,application of thermal wave imaging technology to hidden corrosion inspection was experimentally studied.The results show that this technology is able to reveal hidden corrosion,especially good for exfoliation corrosion,regardless corrosion product remains or not as well as presence of paint on the surface.The image of corrosion has details and is easy to understand.This technology is able to reveal disbond as well as lack of sealant inside bonded joints. |
