Heat treatment / Laser hardening

High power fiber lasers can be used to modify structure of metals (mostly steel and iron) by heating a tiny layer of the material. This process preserves the physical and chemical properties of the base material, but leads to increased wear resistance and extends the lifetime of processed surface.

The thickness of modified layer depends on material type, it’s absorption, surface condition and usually range up to 2mm. Using different beam shaping optical heads allows a precise control of the processed area, speed and depth of modification.

This process was widely adopted in automobile parts manufacturing and tooling.
