Laser
Induced Surface Improvement (LISI):
Basics of Implementation
- select
a property improvement (i,.e. wear, corrosion,
erosion, lubricity, etc.)
- select
a base alloy
- design
an alloy surface that provides the improvement
- form
a master alloy powder blend and apply it to the surface
of the base alloy as a paint or thin film
-
master alloy layer ~ 100-200 microns
- apply
thermal energy via laser optics to melt the master alloy
addition into the top layer of the base material
-
laser optics optimized to achieve uniform heating
- laser
optics dwell time very short, permitting rapid cooling
and formation of refined grain, non-equilibrium
structures
-
new alloy depth into base metal variable from 25-1000
microns
-
fiber-optic laser beam delivery permits precise control
of location
