Air plasma spraying (APS)

technologie_plazmaThere are several types of plasma spraying. We use the Air Plasma Spraying (APS) technique. The nozzle of the burner consists of a tungsten cathode and copper anode. Gas is ionized in the electric arc that burns between the two. This generates a plasma jet into which the spraying material (powder) is introduced, either radially or axially. The material melts and is propelled towards the surface that requires coating.

Spraying parameters:

  • Coating thickness: 0.05 to 0.3 (max. 8.0) mm
  • Porosity: 2-8%
  • Adhesion: 20-70 Mpa

Spraying materials:

  • Metals and metal alloys with low or intermediate melting points
  • Ceramics
  • Cermets
