What is HVOF Coating?

The High-Velocity Oxy-Fuel (HVOF) coating process is used to apply protective coatings to surfaces. The thermal spray coating technique is a popular option because of its superior properties compared to other thermal spray processes.

The HVOF process involves the combustion of oxygen and fuel at high pressures and velocities inside a combustion chamber.

This produces a jet stream expelled through a supersonic nozzle with powdered coating materials onto the workpiece.

This results in a dense, hard, and well-bonded coating on the object.

Some of the main advantages of high-velocity oxygen fuel include the following:

Higher coat density

The coating particles sprayed at high velocity make it dense and well-bonded, making it durable and wear-resistant.

Reduced oxidation

The HVOF thermal spraying processes minimize the oxidation of coating materials, giving them corrosion protection and improving their mechanical properties.

Precise control

The HVOF thermal spray process gives better control over particle velocity, temperature, and spray pattern, resulting in an even coating.
Overall, the HVOF process produces high-quality, high-density coatings with superior bond strength, hardness, and corrosion resistance.

For HVOF coating services – in Texas, industries in the area should make this the preferred choice where protective coatings are needed for component performance and longevity.

Why Choose HVOF Coating?

There are several reasons to choose HVOF coating over other available techniques. Some of the key advantages are as follows:

Superior Durability

Machinery with HVOF coating applications have a longer lifespan and better protection from wear and tear. This is thanks to some of the main attributes of the HVOF process like:

  • High coating density: The dense coating is due to the intense kinetic energy of the sprayed particles, resulting in resistant coatings that can withstand abrasion and erosion.
  • Enhanced adhesion: The high-velocity gas stream allows the particles to bond strongly with the material.
  • Low oxide content: Because of the minimal time spent in high temperatures, the coating retains its original properties better, making it last longer.

Enhanced Protection

HVOF coatings are a robust shield against heat, corrosion, and abrasion. Here’s how:

  • Heat protection: The dense coatings have minimal gaps, acting as a barrier preventing heat from penetrating the HVOF equipment.
  • Corrosion protection: The HVOF also acts as a physical barrier against corrosive agents like chemicals and salt from contacting the substrate material and causing damage.
  • Abrasion protection: The HVOF coating is often composed of carbides, ceramics, and metal alloys that are extremely hard.

Improved Performance

Machinery with HVOF thermal spray coatings are more durable and less prone to damage. This minimizes downtime and allows you to maximize its use by:

  • Reducing friction thanks to its smooth surface.
  • Improving component performance by helping the machinery from overheating.
  • Protecting from corrosion that can cause damage.


While the HVOF equipment comes at a higher investment cost than other thermal spray coatings, the long-term benefits make it a more cost-effective solution.

For HVOF coating, Texas machinery becomes more durable, extending its lifespan. This reduces labor, repair, maintenance costs, and unproductive downtime.

Few thermal spray coatings are as durable and well-constructed as HVOF (High-Velocity Oxy-Fuel) coating. The bond of HVOF coatings is higher than almost any other thermal spray coating around. Because of that, a majority of those who choose to use HVOF coatings have noticed that there is often less wear and tear on their machinery. Aside from that, HVOF coatings are known for having a higher hardness and density, making them nearly five times stronger than plasma spray coatings. This is the heavy-duty type of thermal spray coating you want to choose when investing in protecting your machinery.

Benefits of HVOF Coatings

The first thing that most people note about HVOF coating is the higher cost. While the price point may be higher than some of our other thermal spray coatings, the benefits of HVOF coatings more than make up for the difference. There’s no denying that HVOF coatings are easily one of the most durable thermal spray coatings, especially when compared to some of the other thermal spray coatings available.

HVOF coatings have the highest density and hardness of all thermal spray coatings. They deliver your most critical pieces of equipment the highest level of protection from heat, weather, wear and tear possible. HVOF coatings may be the priciest type of thermal spray coating, but that’s because they offer your machinery the most effective protection and durability available.

Common Applications

Because HVOF coatings are so durable, there are countless ways to take advantage of its capabilities in regards to the application. HVOF coatings are most commonly used in settings where machinery and equipment will be exposed to high temperatures on a regular basis, as it is able to provide the type of protection that machinery needs in these hot settings to avoid severe wear. Aside from that, many of our clients utilize this thermal spray coating on equipment that is used often enough to the point of the machinery itself reaching high temperatures. That is why it’s extremely common to find HVOF coatings on pistons, cylinders, pins, and blades.

Can HVOF coating be applied to any type of machinery?
There are limitations to the types of machinery in which an HVOF coating can be applied. It depends on material compatibility, shape, surface accessibility, and others.
How long does the HVOF coating process typically take?
The HVOF coating process usually takes a few hours to complete. The exact time will vary depending on the size and complexity of the machinery.
What is the maintenance requirement for HVOF coatings?
HVOF coatings have minimal maintenance requirements, but regular inspections, cleaning, and touch-ups may be needed to ensure the coating continues to provide optimal protection.
Can HVOF coatings be painted or coated over?
Yes, as long as the paint or coating is compatible with the HVOF material and doesn’t compromise its performance.

It’s best to consult a professional before applying additional coatings on top of an existing HVOF coating.

How does HVOF coating compare to other surface treatment methods?
Compared to other methods, HVOF coating is considered one of the most effective because of its superior properties, durability, corrosion protection, and bond strength.
