HVOF - High Velocity Oxygen Fuel

Using high-velocity oxygen fuel (HVOF), we can spray a wear and corrosion-resistant coating onto a surface in the blink of an eye. The result: a super-strong protective layer that can withstand wear and corrosion.

Basic principle

High Velocity Oxygen Fuel

HVOF uses a burning gas flow created by mixing oxygen and a fuel and igniting it in the spray gun. A metallic powder is then added into the mix, and upon colliding with the surface, these metallic particles form a dense and homogeneous coating with high adhesive strength and limited internal tension. The remarkable thing is that despite the relatively low temperatures used (3000 °C), the coating adheres to the surface extremely well due to the high impact speed. This allows the coating to reach extremely high levels of hardness and lends it excellent corrosion and wear-resistant properties. The limited pore volume and excellent adhesive properties of the HVOF coating make this technology an effective solution to protect surfaces against wear and corrosion.


  • High tensile strength
  • Dense/pore-free coating
  • High level of hardness
  • Extremely good protective qualities (erosion, abrasion, fretting etc.)
  • Low oxidation during the process


  • Improved performance
  • Less downtime
  • Longer lifespan
  • As good as no limit on how often parts can be re-engineered

Available coatings

  • Carbide materials (hard metals, tungsten carbide, chromium carbide)
  • Hard chrome replacements
  • Pure metals (copper, nickel, aluminium etc.)
  • Molybdenum
  • Inconel, Hastelloy, Stellite, Colmonoy, titanium
  • Self-fluxing alloys (Ni-Cr-B-Si)
  • Cermets


Machine parts for which:

  • improved electrical properties are required;
  • the application operates at extremely high or low temperatures;
  • the operating environment is highly chemically aggressive;
  • the service life needs to be expanded;
  • a carbide coating needs to be applied;
  • the hard chrome needs to be replaced;
  • a wear-resistant and extremely smooth surface is required (grinding);
