Electric arc spraying

technologie_el_obloukAn electric arc burns between two metallic wires, which produces molten particles of material. These particles are propelled by compressed air towards the surface that requires coating.

Spraying parameters:

  • Coating thickness: 0.1 to 2.0 (or more) mm
  • Porosity: 2-8%
  • Adhesion: 35-45 Mpa

Spraying materials:

  • Pure metals and metal alloys
