Non-Destructive Testing of Hardened Carbon Steel Using Frequency Sweeping Excitation and Spectrogram Method

Abstract:

In this paper, we present a frequency sweeping excitation and spectrogram method (FSES method) for non-destructive testing of hardened carbon steels. The FSES method can evaluate the electromagnetic properties in materials which were changed after induction heating. Therefore, it’s possible to evaluate the hardening conditions using the FSES method. We applied our method to the practical car seat parts to use in actual products. The surface of the hardening sample is deformation by the induction heating. We show the method that can evaluate the hardening conditions without being influenced by the surface deformation.
