HVOF Systems

A Pioneer in High-Velocity Oxygen Fuel (HVOF) Cylinder Rod Resurfacing 
Applied Fluid Power has invested in the best equipment available to bring you the cleanest and most environmentally-friendly thermal spray method for hydraulic actuators. The HVOF process utilizes a material in powder form that is injected into a flame of supersonic gas. The material softens in the flame and forms a dense coating on the substrate. 
  
Improving Your HVOF System Performance 
The HVOF process eliminates the use of chromic acid solutions, which are known carcinogens and can cause a host of other health problems. It also improves performance of cylindrical metal parts, dramatically lengthening component and seal life.  
  
This coating: 

  • Reduces corrosion and rust on the surface of the component 
  • Increases impact resistance 
  • Is believed to be the safest and most effective protection coating in the marketplace

Estimated cylinder life improvement is as high as five times that of chrome, which means less opportunity for downtime.

Our HVOF Process

The High Velocity Oxygen Fuel (HVOF) coating process starts by mixing fuel and oxygen, igniting them in a combustion chamber. This generates a high-temperature, high-pressure gas, which is then expelled through a nozzle at supersonic speeds. Next, powder is injected into the stream and propelled onto the substrate, resulting in a coating with low porosity and a strong bond to the substrate, offering excellent wear and corrosion resistance. A big advantage of this process is its ability to create dense and hard coatings at relatively low temperatures.
