The technology of thermal spraying permits the manufacturing of adapted surfaces for each application by local deposition of coating materials with optimized properties. 


Due to the various possibilities to combine coating and substrate materials and due to the large variety of processes and achievable processing conditions, thermal spraying is of utmost significance among the coating processes.

In various applications it offers perfect solutions regarding surface technological problems.

  • Overhaul / repair
  • Wear protection
  • Corrosion protection
  • Bond coats
  • Electrical isolation
  • Thermal isolation
  • Clearance control (Abradable Coatings)

Due to the diversity of processes and spraying materials the technology of thermal spraying offers adapted solutions for a wide range of application fields. GTV offers the full spectrum of feedstock powder with different morphology, size fractions and chemical composition. Thereby the user is enabled to exploit the full potential of the thermal spray technology.


Spraying powder is available in very different size fractions and with different morphologies. Both properties take significant influence e.g. on the flowing characteristics, the melting behavior and potential micro-structural transformations during the spraying process or subsequently performed heat treatments. The consequence of bad powder flow characteristics are fluctuations in powder feeding and thereby induced inhomogeneities in the produced coatings microstructure. Therefore, even for use of fine powder size fractions minimum flow characteristics need to be maintained.

The melting behavior has to be evaluated with regard to the desired heat transfer into the powder particles. The degree of melt formation in single particles determines e.g. the intensity of chemical reactions like oxidation or reactions of different powder constituents as well as phase transformations during spraying. 


The powder particles morphology is a result of the powder production route and the applied processing. The majority of common spray powders is produced via four different routes.


  • Fused and crushed powders
  • Water or gas atomized powders
  • Agglomerated and sintered powders
  • Clad powders

To ensure optimum material and coating properties, we have a wide range of in-house equipment at our disposal. This includes:


  • Cilas laser diffractomy
  • Camsizer X50 particle analysis
  • Sieve analysis using sieve tower
  • Scott Flowmeter, Hall Flowmeter
  • Optical microscopy
