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
