Surface Treatment Technologies, Inc.

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
