Delivering superior wear resistance and corrosion protection for aerospace, oilfield, and industrial applications. Trust us to enhance performance and extend the life of your critical parts.
Unmatched Durability for Industrial Excellence
High-Velocity Oxygen Fuel (HVOF) thermal spray propels molten or semi-molten carbide and metal particles, like tungsten carbide or nickel alloys, onto a surface at supersonic speeds (up to 2,000 m/s). A fuel-oxygen mixture burns in a combustion chamber, creating a high-pressure gas jet that heats and accelerates the coating material. This forms dense, low-porosity coatings with exceptional wear resistance and corrosion protection, ideal for oilfield, and other industrial components. Longevity Coatings delivers durable, high-performance solutions.
In fact, the hardness, corrosion resistance, and overall wear resistance of these coatings are often superior to plasma coatings. In HVOF, the gases go through a converging diverging nozzle, with gas velocities reaching a velocity near 8000 fps. Which is particularly crucial when applying a tungsten carbide coating.
Common HVOF Coating Materials
