Introduction
Induction hardening is a fast, energy-efficient heat treatment that selectively hardens the surface of metal components using electromagnetic induction. By focusing heat only where it’s needed, this process delivers enhanced wear resistance and fatigue life while keeping the core ductile and distortion to an absolute minimum.
Key Benefits
-
Localized Hardening
Precisely targets critical wear zones without affecting surrounding areas or entire workpieces. -
High Precision Temperature Control
Rapid induction coil heating ensures uniform, repeatable hardness profiles. -
Minimal Distortion
Quick heating and quenching cycles reduce thermal gradients, preserving tight dimensional tolerances. -
Improved Fatigue Resistance
Hardened surface layer strengthens against crack initiation and propagation under cyclic loads. -
Energy & Time Efficiency
Faster cycles and lower energy consumption compared to furnace-based methods.
How It Works
-
Fixturing & Masking
Secure parts in a coil fixture; apply heat-resistant masks to protect non-hardened areas. -
Induction Heating
Electric current flows through the coil, generating an alternating magnetic field that heats the surface to the austenitizing temperature. -
Quenching
Immediately spray or flood with quench media (water or polymer) to transform the heated layer into martensite. -
Final Inspection
Measure case hardness, depth, and perform microstructure checks to confirm process accuracy.
