High Velocity Oxy-Fuel Spraying [HVOF]

HVOF Spraying is essentially a variation of powder flame spraying in which a modified torch is used to constrict the gas flow.   This produces an extremely high velocity flame that is similar to that of a jet engine. HVOF coatings are usually denser and have higher bond strengths than coatings produced by other processes. These features are

particularly useful when a tough, wear resistant coatings such as tungsten carbide is required. NCT uses HVOF spraying to produce wear and erosion resistant coatings on fan blades and other machinery components exposed to severe service.
