Adding coatings to components has a range of performance benefits. However, to make the most of this process, you have to choose the right coating technique. In some cases, a high velocity oxygen fuel (HVOF) coating is the best solution. How does this coating work and what advantages does it give you? 

How Does the HVOF Coating Process Work?

HVOF coatings are typically applied via a thermal fuel and oxygen torch system. The tool's fuel and oxygen go through a combustion process to ignite. This creates a highly pressurized and hot gas.

When a coating powder is added to this gas, it sprays out of the tool's nozzle at high speeds and at a high temperature. The powder clings to the surface instantly. Unlike some other coatings which take time to dry and set, this type of coating turns solid almost as soon as it hits the surface.

Why Use HVOF Coatings?

If your aim is to give a component or part some extra protection or to repair areas of damage, then an HVOF coating could be the answer you're looking for. These coatings create high-quality and tough finishes with a long lifespan.

So, for example, if you need to give a component extra protection because it will come into contact with temperature extremes or chemicals, then an HVOF coating gives the surface an extra layer of useful protection. The coating will shield its underlying surface from damaging environmental conditions and substances.

These coatings also protect against usage problems that might compromise the integrity of a part such as wear, rust, and fatigue. The bond between the coating and its surface is strong and tight. It won't wear or get damaged even on load-bearing surfaces.

You also get more control over how coats go on to a surface with this technique. It is easy to create a uniform layer on a component or part even if it is an odd shape. You can even use this process to repair current damage.

For example, if you have a part that has worn down so much that it doesn't work well any longer, then an HVOF coating can cover the worn area. You can control the thickness of a coat relatively easily. So, you could put a thicker layer on a worn area to build it back up and a thinner layer on the rest of the part.
