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
