True contour gear hardening pattern can be obtained utilizing this technology. Single-shot hardening of several powertrain components utilizing dual frequency systems dramatically minimizes distortion of induction hardened parts and provides a superior hardness pattern with favorable distribution of residual stresses.

Some induction practitioners have heard about simultaneous dual frequency gear hardening. Coil current waveform comprises two appreciably different frequencies making effect of two single frequency inverters working on the same coil at the same time.

Accurately controlled induction heat treating systems are effectively used for induction hardening large gears and bearing races utilized in wind energy applications.
