Abstract:The working principle of pulsed eddy current (PEC) nondestructive testing technology is analyzed, The PEC testing system was been established to examined the specimen of multi-layered aircraft structure, peak and zero-crossing time of the time domain transient response signal of PEC are extracted as the features to detect the corrosion in the second layer of aircraft structure quantificationally, the experiment results are consistent with that of the theory analysis, as the PEC have the advantages of fast speed and quantification, this makes the method have the broad using foreground in the testing of aircraft structure corrosion.
Keywords:pulsed eddy current  nondestructive testing  corrosion  peak  zero-crossing time
