CONCEPT
Laser heat treating is a process in which a laser beam (with a typical laser spot size from 0.5” x 0.5” to 2” x 2”) is focused onto the metal surface being treated. With proper control, the incident laser energy raises the surface temperature of the metal above its martensitic transformation temperature. When the laser beam is switched off, the metal’s thermal mass aids in rapid ‘self-quenching’ (by removing the heat via conduction), resulting in the formation of the desired martensite microstructure, thus giving the material its required hardness and wear properties.
