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.

Advantages of laser hardening
- High precision: Laser hardening enables selective hardening of specific areas, which minimises the risk of cracks and distortion.
- Minimal post-processing: Due to precise heating and rapid cooling, the need for post-processing is minimal.
- Low environmental impact: The process is energy-efficient and has a low carbon footprint.
- Versatility: Laser hardening can be used on various materials, including cast iron and tool steels.
-
Application areas
- Automotive industry: For hardening parts such as gears, shafts and other components that require increased wear resistance.
- Machinery industry: Used for tools and moulds where high strength and wear resistance are critical.
- Aerospace industry: Hardening components that are exposed to extreme conditions.
- Medical devices: To improve surface properties of implants and instruments.
- Transport equipment: Used to harden parts exposed to heavy loads and wear, such as sliding surfaces and guide tracks.
