Electro-Spark Alloying: Technology Overview and Applications

ESA Parameters

 

Deposition of alloys

  • consumable electrode
  • capacitive discharge melts and
    accelerates electrode material
    onto workpiece
  • produces a metallurgical bond
  

Low heat input

  • pulse time is extremely short
  • interval time >100x the pulse time
  • produces a very short duty cycle and no heat accumulation in workpiece
