Résumé :

The application of Pulsed eddy current (PEC) in the industrial domain is very weak compared to conventional eddy current. It is used in detection of the defects, particularly in the determination of corrosions .The information contained in the receivedsignal gives the possibility to determine several parameters withthe objective of analyzing material. The results explain the behaviour of the Pulsed Eddy Currents and their influences invarious electromagnetic parameters. We have evaluated in particular the aptitudes and the performances of this technique in the determination of the materials characteristics. we haveAlso studied the sensitivity of the defects by the pulsed methodand we have showed the detection of the defects into the second and third layers. The application of NDT by PEC methods can characterize microstructure types, micro structural changes, and can be correlated tohardness changes. The objective of our work is to evaluate some metallurgic characteristics by non-destructive methods.
