Laser Heat Treatment
|
Laser heat treatment (sintering, ablation) rasters or focuses a laser over a specific area. It is a surface modification process that is designed to change the microstructure of metals by controlled heating and cooling. The heat-treated area can be highly selective because lasers are able to heat treat precise areas of metals without involving the entire workpiece. With laser heat treatment, the mass of the material being processed is generally sufficient for rapid heat removal or "quenching ". The enhanced mechanical properties resulting from laser heat treatment depend upon the specific composition of the metal or alloy. Laser case hardening of transformation hardenable metals provides high wear and abrasion resistance with a minimum of distortion and cracking. Laser spot annealing of precipitation and work hardened metals, such as 300 series stainless steel and copper alloys, restores ductility and improves formability and fatigue resistance in critical areas.
