Multiphysics Modeling of Induction Hardening of Ring Gears for the Aerospace Industry

Abstract

Induction heating has been widely used for heat treating and especially surface hardening in a broad variety of applications, ranging from the automotive to the renewable energy market. However, the lack of precise knowledge about the interrelation between all the concurrent physical phenomena occurring within the part during the heating cycle has restricted its use to mass-production items (mostly gears). The benefits of this technology, which is clean, repeatable, and cost-effective, could boost its introduction into more conservative industry sectors, such as aerospace, where furnace-based treatments (e. g., carburizing) represent the golden standard. The major limitation is related to the optimization of the induction hardening process, which usually requires significant material know-how and can thus be very long and expensive. Computer simulation could provide a general tool for understanding and improving the critical aspects of each step of the process, thus speeding up the spreading of the induction technology into new markets

The Influence A Crucible Arrangement On The Electrical Efficiency Of The Cold Crucible Induction Furnace

“…It combines the electric vector potential T and scalar magnetic potential for conductive areas (both magnetic and non-magnetic) with formulated for non-conductive magnetic areas and reduced scalar magnetic potential r for non-conductive and nonmagnetic areas [32][33][34][35].…”

The Use Of Multifrequency Induction Heating For Temperature Distribution Control

“…Obviously, more complex and complicated objects affect the choice of the proper process and its parameters. Gear hardening processes have been conducted for many years [11][12][13][14]. However, although the induction heating process is well described in references and used in many metallurgical technologies, its application for hardening of gear wheels is still rather rare.…”

Single-Sided Electromagnetic Induction Heating Based on IGBT

“…In the high-frequency heating applications, the heating coils are the first things to consider; we need to choose the right material and winding shape [13]. The coils should be based on the current flowing through the coil to be determined.…”
