Laser Induced Surface Improvement (LISI)

  • controlled surface modification via high energy laser
  • specific area modification
  • not a coating, but a re-alloying of the base metal surface
  • surfaces are integral to the base alloy, do not delaminate
  • current alloying rates ~ 20 ft. sq./ hr. per laser
  • environmentally friendly

Electro-Spark Alloying (ESA)

  • controlled surface modification via pulsed micro-welding
  • coating is fused to base alloy, do not delaminate
  • coatings are nano-composite structures with unique corrosion
    and tribological properties
  • current coating rates ~ 1-2 ft. sq./hr. per system
  • environmentally friendly

Rapid Arc™

  • controlled surface modification via rapidly pulsed fusion welding process
  • lower arc voltages, lower heat input
  • minimal heat affected zone (HAZ) in substrate
  • true metallurgical bond with substrate
  • reduced dimensional distortion of part
  • versatile, user-friendly operation
