Abstract

Induction surface hardening, which is used in various fields in the aerospace industry, is an important technology due to its accuracy, repeatability and energy efficiency. By modeling this heat treatment, the process parameters and efficiencies will be understood and its effective use in critical aircraft application areas will be expanded by contributing to the development of this technology. In this study, the induction surface hardening process of the cylindrical sample from AISI 4340 steel was simulated using couple field analysis. The coil geometry was optimized using two approaches to achieve homogeneous temperature distribution on the heated sample surface. One is to change the diameter of the coil rings and the other is to change the interval of the coil rings. After the diameters of the coil rings optimization, uniformity was achieved at the sample surface temperature, with deviations up to ±4°C from the austenitizing temperature. After the interval of the coil rings optimization, homogenous temperature distribution was achieved at the sample surface temperature, and deviations from the austenitizing temperature were up to ±3°C. The current value required for heating the sample surface to the austenitization temperature in 2s has been reduced, and energy savings have been achieved.
