Title : ( Application of harmonic analysis for determination of hardened depth in surface heat treated parts )
Authors: Saeid Kahrobaee , Mohammad Hosein Nateq , Mehrdad Kashefi Torbati ,Abstract
Frequency domain evaluation of eddy current signals (harmonic analysis) in ferro-magnetic materials has been introduced in the last years as an industrial tool for materials characterization and proved to be a reliable and cost effective alternative to traditional techniques of quality control (metalography, mechanical tests, etc.). In the present study, identical rods of AISI 1045 mild carbon steel, case hardened using induction hardening method. Plotting hardness profile, effective and total case depths were also determined. In order to investigate the applicability of this nondestructive method, relations between case depths and calculated quantities of harmonic analysis on eddy current signals were studied. High correlation coefficients of these relations indicate an acceptable level of accuracy in comparison with destructive method
