概要
This paper aims at a detecting corrosion on the back surface of a ick steel plate. Our proposed technique is characterized by using pulsed eddy current testing with DC magnetization. The thick steel plate is magnetized by DC Magnetizer. Therefore the magnetization g erates the magnetic flux in the plate. The permeability of the plat e changes with the corrosion. Changes in the permeability of the pl ate are detected by pulsed eddy current testing. The corrosion on e back surface of the plate was detected in experimental results.
