Electro-Spark Alloying: Technology Overview and Applications

ESA Surfaces for Wide Range of Applications

Wear Resistance

  • Hard Carbides (of W, Ti, Cr, Ta, Mo, Hf, Zr, Nb, V)
  • Hardfacing Alloys (Stellites, Tribaloys, Colmonoys, etc.)
  • Borides (of Ti, Zr, Ta)
  • Intermetallics and Cermets

Corrosion Resistance

  • Stainless Steels
  • Special Alloys (Hastelloys, Inconels, etc.)
  • Fe, Ni, and Ti Aluminides

For Build-up or Special Surface Modifications

  • Ni-base and Co-base Super Alloys
  • Noble Metals (Au, Ag, Pt, Pd, Rh)
  • Refractory Metals and Alloys (W, Mo, Ta, Re, Nb, Hf)
  • Other Alloys (Fe, Ni, Cr, Co, Al, Ti, Cu, Zr, Zn, V, Sn, Er)
