This technology was developed by Russian scientists in the mid 1980s. Minute metallic particles bond with a substrate when they impact its surface at supersonic speeds. The discovery that metallic particles could bond based solely on their kinetic energy was investigated further in later years and ultimately, the technology was developed under the name Cold Spray.

Because the adhesion of the metals is not based on a melting process, this technology eliminates all the detrimental heat-related effects, e.g. stresses and strains, associated with other thermal processes. Cold Spray technology is viewed as being the newest member of the thermal spray family, yet can be regarded as being in a class of its own thanks to its unique characteristics.

Technology and coating characteristics:

  • Rapid, localized coating build-up without any direct effects on the work piece's surrounding areas
  • Work piece and coating material remain virtually cold
  • High-grade coatings – ultra-strong bonding and high density
  • Bonds with all common metals (steel, aluminium, cast iron, etc.), ceramics and glass
  • Coatings of up to 5 mm thick, ready for immediate finishing
  • Aluminium, zinc, copper, tin, nickel and Babbitt coatings

DYMET Cold Spray System
This metal coating system is unique in Europe by virtue of its user-friendliness and countless practical applications.

The process is perfect for repairing all sorts of damage sustained by metal components, e.g. knocks, dents, scratches, rust spots, cracks, etc. Depending on the situation, it is even possible to make temporary or permanent repairs where it would otherwise cost too much and/or take too long (downtime) to replace the part.


  • Suitable for all regular power supplies (220 VAC, 3.3 kW) and compressed air supplies (6 bar)
  • Lightweight (18 kg) and compact size (55 × 26 × 48 cm), i.e. portable!
  • Extremely easy to use
  • Ready to spray metal within 10 seconds
  • Surface pre-treatment is often unnecessary thanks to the technology used
  • Quick and simple conversion for blasting using the same system
  • Manual and/or automated operation
