Laser Alloying

Laser Induced Surface Improvement

Technical Advances

  • Permits precise selection of area to be modified
  • Requires a very small amount of modifier alloy
  • Results in extremely rapid heating and cooling of the surface
  • Produces wide variety of chemical and microstructural states outside of typical phase diagrams
  • Produces no distinct bondline; will not delaminate
  • Requires little or no surface preparation for certain applications
  • Produces minimal hazardous waste stream
  • Performed remotely with robotics and fiber-optics
  • Performed at rates between 20-50 sq.ft./h
