Benefits of induction surface layer hardening compared to other hardening processes

Published 13 October 2016 | By EMAG eldec Induction GmbH

Induction surface layer hardening is an electrothermal process used in the industry for various workpieces, such as gear wheels and shafts.

As the name suggests, induction surface layer hardening does not harden the entire workpiece, only the surface area.

This means, for example, that while the teeth on gear wheels are very hard, the core of the workpiece continues to have a certain amount of elasticity to enable it to deal with impact-type stresses such as those that occur on gearbox components.
