About the process:
A surface hardening process whereby heating is done by induced electrical current. A high-frequency electrical current flows through a copper coil, producing a magnetic field around the part. No change in material chemistry occurs during processing. Using this process, case thickness (hardened layer) can be closely controlled.
Advantages:
- Cost savings include ability of manufacturer to substitute alloy steel for carbon steel; elimination of straightening and machining operations; and an automated, efficient hardening operation
- Metallurgical advantages include: improved fatigue strength; increased wear resistance; and uniform control of hardness and hardened pattern
