HVOF Coating

High-Velocity Oxygen Fuel (HVOF) coating is a thermal spray process that applies exceptionally durable and high-quality coatings to surfaces. The process works by accelerating a mixture of oxygen and fuel through a specially designed nozzle. This generates a supersonic jet that propels coating materials at extreme velocities onto the target surface. This high-speed application produces coatings that are remarkably dense. They contain significantly less oxide content than those created by other thermal spray methods. As a result, HVOF coatings deliver outstanding resistance to wear and corrosion, providing long-lasting protection even in harsh industrial environments. For industries seeking reliable and enduring surface solutions, it is industry standard.

At Longevity Coatings, we specialize in providing top-tier HVOF solutions. With decades of experience and a commitment to quality, we ensure that every coating meets the highest standards of performance and durability.

Benefits of HVOF Coatings

Our HVOF coating services offer a range of advantages:

Superior Wear Resistance: The high-velocity application ensures a strong bond, making HVOF coatings perfect for demanding environments.
Low Porosity: hvof coatings have lower porosity than other thermal spray processes.
Corrosion Resistance: Shield your components from harsh conditions.
Material Versatility: Compatible with metals, alloys, and carbides.
Lower oxygen content: The coating has lower oxygen content. Due to the short dwell time and relatively low temperatures reduce oxidation during the process.
