Laser Surface Treatment
Lasers are good heat sources often used for surface hardening of various tools and surfaces. This heat source causes the metallographic structure to change and hardens the surface to provide increased wear resistance.

The choice of laser to be used for surface hardening is mainly dependent on the parts itself. Most hardening applications require CW beams, such as in track hardening of most industrial tools. Some intricate/small parts that require hardening use pulsed lasers. Typically any laser can be used for hardening applications, as the main parameters is the power that is required to harden the material to desired depth and hardness. The advantages of using fiber lasers for hardening applications are the fiber delivery, high wall plug efficiency, compact size and high powers offered by the direct diode and Ytterbium lasers.

Application Examples:

  • Track hardening of threads on industrial tools
  • Turbine blade hardening
  • Piston rings

Typical lasers for this application include:

DLR Series: Direct Diode Fiber Pigtailed Laser Systems Operating @ 980 nm  

YLR HP Series: 500 W-20 kW Multi Mode High Power Ytterbium Fiber Laser @ 1070nm
