Laser hardening

Laser hardening of a shaft with parallel spirals.

Laser hardening is a surface hardening process that generates maximum hardness values at the component surface with a very low energy consumption.
The heat input is by laser beam for a short time and locally limited. The quenching takes place via the heat dissipation in the component, no separate quenching medium is required.

Advantages of laser hardening:

• high surface hardness with tough core material
• low distortion process
• constant surface temperature
• Quality control during the process with time parallel documentation
• energy efficient and environmentally friendly
• no quenching media required
• also suitable for small series and individual pieces
