Employing the simulation platforms Flux 2D and FEMM4.2 to numerically optimize the eddy current phenomenon during the edge-hardening process

This paper aims to develop advanced numerical methods for an in-depth examination of edge hardening process, using eddy current heating. We present a distinct procedure for heat treatment, in our attempt to achieve a particular thermal profile, defined by a higher level of heating in the tip area of the workpiece, compared to the remainder of the piece surface. In order to ensure the necessary mechanical strength, this targeted method applies selective hardening to the tip area, while maintaining the elasticity of rest of the part, so as to ensure the required mechanical strength. The fundamental objective of the work is to present advanced models for optimizing the inductor input parameters in order to achieve a differentiated and efficient heating of the workpiece tip. The precise control of the hardening process and the enhanced mechanical performance of the workpiece are two major implications of this approach.
