HVOF, literally means high velocity oxygen fuel, is a thermal spray coating process, which is used to improve a component’s surface. This coating surface improves the properties of anti-corrosion, wear resistance and high temperature resistance and definitely extends the life of equipments. This technique is becoming more and more popular, especially used in hydraulic cylinders which are used in harsh environment like offshore projects and mining.

HVOF coatings are typically high-hardness materials such as tungsten carbide, chromium carbide, or other metals. HVOF-applied Tungsten carbide coatings are the hardest and most wear-resistant, while chromium carbide coatings offer wear resistance at high temperatures. Coatings applied by the High-Velocity Oxy-Fuel process exhibit density, hardness, and bond strength characteristics that can significantly outperform other methods of application and can significantly increase wear resistance and increase erosion protection. In most cases, spraying is performed in fully automated robotic coating cells for high accuracy and repeatability.
