Robotic Cold Spray

Spray 01 Spray 02 Spray 03

 

The uniqueness of Cold Spray technology lies in its ability to produce a coating at relatively low temperature, thereby avoiding or minimising many negative high temperature reactions which are characteristics of typical thermal spray coatings:

  • High Nickel spray
  • Tungsten Carbide spray
  • Ceramic spray
  • Aluminium spray
  • Dissimilar materials spray
  • Hard facing spray
  • Corrosion resistant spray
