Laser Hardening
Laser hardening is an ideal surface modification technology for highly stressed and/or complex components made out of a ferrous material suitable for hardening. The process produces the highest hardnesses achievable for the selected steel or alloy with practically no warping. The laser heat input is very targeted and confined to local areas. The heating and cooling is so rapid that no external quenching is required. Laser hardening is typically used for cutting edges, sharp corners, pockets or other important geometrical part features.
