Identification of corrosion fringe in pulsed eddy current nondestructive testing

Chinese Journal of Mechanical Engineering, 2008
It is difficult to accurately identify corrosion fringe in nondestructive testing (NDT),which will directly influence the effect of corrosion imaging.Array pulsed eddy current (APEC) is used to detect corrosion.With the purpose of overcoming the problem of low identification accuracy in conventional NDT which only extracts features in the time domain ...
