Laser hardening

Laser Hardening
Laser hardening is a method for selectively increasing the hardness and wear resistance of metallic materials. This technique offers high precision and minimal distortion, making it ideal for components that require local hardening without subsequent machining. During laser hardening, the surface is quickly heated by the laser beam to a temperature where the material transforms into austenite. It is then rapidly cooled by the surrounding material, resulting in a hard martensitic structure. This process produces a surface with high hardness and wear resistance while retaining internal toughness. Almost all types of steel gain increased hardness after laser hardening.
