In this episode, Jason Church speaks with Curtis Deselles, an intern with the Materials Research program at NCPTT, discusses the use of eddy currents and eddy current technology in conservation science. Mr. Deselles has built several eddy current analyzers, custom software, and presented on this topic at a non-destructive conference in St. Louis.

NCPTT has been using eddy current technology in preservation and will be bringing this tool to the iPhone platform in 2010. Download Episode 8 as an mp3 or subscribe via iTunes.

The topic is the use of eddy currents for identification of metals (ferrous and non-ferrous), measuring the thickness of corrosion, and the recovery of serial numbers and/or images beneath corrosion.

NCPTT’s Curtis Deselles, a graduate student in the Masters of Heritage Resources program at Northwestern State University of Louisiana, is developing a handheld metal tester using eddy current technology.
