Thermal coating technology team

Atmosphärisches Plasmaspritzen einer keramischen Wärmedämmschicht auf einer Turbinenschaufel

The team develops thermal coating technologies focusing on thermal spraying processes. Various state-of-the-art industrial coating equipment is available covering a wide range of materials and applications. Powders, suspensions, or solutions are used as feedstock. Available thermal spray processes:

• Cold gas spraying (CGS), aerosol deposition
• High velocity oxy-fuel spraying (HVOF)
• Atmospheric plasma spraying (APS)
• Low pressure plasma spraying (LPPS)
  LPPS-Thin Film (LPPS-TF)
  Plasma spray-physical vapor deposition (PS-PVD)
  

Plasma and particle in-flight characteristics are analyzed to gain understanding of the process and to ensure quality. Available diagnostic methods:

• Plasma: enthalpy probe, optical emission spectroscopy
• Particles: in-flight temperatures, velocities, and diameters, shadowgraphy of the particle flux

• Stresses: in-situ measurement by curvature analysis
