There are four popular heating concepts used for the induction spin hardening of gears that employ encircling-type coils: the conventional single-frequency (CSFC), pulsing single-frequency (PSFC), pulsing dual-frequency (PDFC) and simultaneous dual-frequency (SDFC) concepts. All four modes can apply either a single-shot or scanning approach. Click here for more information.

Induction does not promote any appreciable corrosion. However, it is well-established that corrosion intensity increases with increasing temperature (regardless of whether the temperature increase is after induction heating or any other heating means, assuming that the rest of conditions remain the same). Therefore, if selected regions of the heat treated part have different temperatures, then [...]

Coil copper overheating is another common cause of coil failure. Relatively small coil-to-gear gaps lead to appreciable thermal radiation from the heated surface. This factor in combination with a very limited space allowed for water cooling of the coil can result in copper overheating, particularly when the scanning mode is used for hardening. Both tooth-by-tooth [...]

Compared with brazing and soldering, adhesive bonding is much more versatile because the components to be joined do not have to be metals. Plastics, ceramics, glasses, and other nonmetallic materials also can be bonded. The adhesive, which is applied prior to induction heating, is not electrically conductive, so it cannot be heated by induction. Therefore, [...]
