Supersonic Coatings for Unmatched Durability and Performance
High Velocity Oxy-Fuel (HVOF) Spraying
High Velocity Oxy-Fuel (HVOF) Spraying is an advanced thermal spray technology designed to create dense, highly bonded coatings with exceptional wear and corrosion resistance. By utilizing supersonic flame speeds, this process delivers superior protection for industrial components, extending their lifespan and improving performance in demanding environments. Ideal for industries such as manufacturing, aerospace, and oil & gas, HVOF spraying ensures reliability and durability even under extreme conditions.
HVOF(High Velocity Oxy-Fuel)
In HVOF spraying process, the pressure in the combustion chamber of the spraying gun is increased to generate high-speed flame comparable to detonative combustion flame. The powder materials are feed and melted, or half-melted in the flame jet stream, then accelerated and continuously sprayed at supersonic speed.
This process allows the formation of coating with extremely high density and high bonding strength. Compared with detonation spraying, HVOF coating has more homogeneous characteristic for its continuous formation process, and exerts more effectively in forming wear resistant coatings with carbide cermets.
