Corrosion characterisation using pulsed eddy current sensor systems

Abstract

Pulsed Eddy Current (PEC) has been applied to characterise atmospheric corrosion on steel samples. Coated and uncoated mild steel (S275) samples with different marine atmospheric corrosion have been supplied by International Paint®. After introduction of pulsed eddy current systems, different measurement on different samples have been undertaken. Experimental results using pulsed eddy current sensor systems and feature extraction on corrosion classification and corrosion progression are reported. In conclusion, PEC testing has potential for corrosion characterisation and monitoring in industrial fields where corrosion is an important problem, e.g. the marine industry.
