Laser Hardening

About the method

Details can be hardened in selected areas with very high precision. The method can be used on components made of so-called hardenable materials such as cast iron and tool steel. Suitable applications are parts that need to be partially precision hardened, such as cutting and shaping tools.



The method is based on the surface being rapidly heated by the energy from the laser beam. Thereafter, the heated zone is effectively cooled by the surrounding base material. The high precision of the laser beam means that any shape changes will be very small and thus the need for post-processing will be minimal. The method provides lower friction compared to other surface hardening methods. 


  • Details can be precision hardened in selected areas
  • Excellent anti-wear properties
  • High load capacity on the surface layer
  • Minimal shape changes
  • Lower friction on surface layer
