Electric arc spraying - ARC

Electric arc spraying is characterised by two electrically conductive wires that are transported through the gun. An electric arc is created between the ends of the two wires that cause the wires to melt. Compressed air transports the melted material to the substrate where it forms a coating.
This process can be used to apply coating quickly and with low energy costs. The benefits of electric arc spraying are the large spray capacity and excellent bonding.
Some characteristics:
  • Microporous lamellar structure
  • Excellent bonding and density of the layer
  • High production capacity
  • Low heat input in product to be injected
Typical coatings:
  • Various stainless steel alloys
  • Inconel alloys
  • Wolfram carbide alloys
  • Nickel-based alloys
  • Copper and copper alloys
  • Aluminium
  • Zinc
