HVOF coating services

HVOF coating servicesHVOF, or High-Velocity Oxygen Fuel coating, is an extremely high-pressure mechanism to realize coatings with high density.

The high velocity refers to the speed and power that this tool can provide. Oxygen fuel refers to the fact that oxygen and a combustible gas, are mixed in a secure chamber inside the pressure gun.

It literally creates an explosive force, blasting a high pressure and extremely hot stream out of the nozzle. The gas can reach speeds of 2200 meters per second with the particles in the gas hitting 700 meters a second, that is in excess of Mach 2.

The gun incorporates a secondary chamber that releases the powder used for coating any product. This powder is melted by the heat generated by the combustion of the process gases and flung at the surface of the intended product.

Why Use HVOF?

The simple answer is to create a coating that is dense, has maximum adhesion, and offers the best possible protection.

In short, it will boost the longevity of any product and provide a stylish finish, if desired.

It is also surprisingly quick to apply to any product and offers minimal environmental damage, especially when compared to alternatives such as electroplating.

What is HVOF Used For?

HVOF can be used for anything as it is effective at coating any product with a compound that will resist corrosion and aggressive wear and tear.

Although it can be used anywhere, the primary targets are:

  • Valves, pumps, and seals
  • Bearings
  • Tools
  • Landing Gear
  • Rocket parts
  • Traction rollers

That’s just a few of the potential applications. In effect, any item that is subject to extreme temperature or excessive and repetitive movements will benefit from using HVOF coating.
