Induction surface hardening - comparison of different methods

摘要

The overview of the induction surface hardening methods were presented in the paper. Two examples are considered: continual hardening of cylinders made of steel 38Mn6 and dual frequency hardening of gear wheels made of steel 40 HNMA. Results of measurements provided at the experimental stand were presented. Acceptable accordance between measurements and numerical computations were obtained. Final conclusions were formulated.
