HVOF

Durable and corrosion-resistant surfaces for demanding environments

Wear- and corrosion-resistant surfaces are needed to protect critical components in various industries. The High Velocity Oxygen Fuel (HVOF) process supplies this protection by producing very dense, hard coatings with fine microstructures.

Whether it is to extend the lifespan of critical components or minimize downtime, HVOF is the obvious choice for the industries of the future.

Common applications for HVOF spray:

  • Valves and seats in the oil & gas industry
  • Equipment for the offshore industry
  • Components for the mining industry
  • Pulp and paper mills
  • Turbine components
  • Aerospace industry
  • Automotive industry

Process overview:

  • Heat source: Combustion
  • Feedstock: Powder form (metals, alloys, carbides)
  • Flame temperature: Approx. 2 800 °C (5 000 °F)
  • Particle velocity: 400–800 m/s (1 300–2 600 ft/s)
  • Approximate application rate: Approx. 40–200 g/min (5–26 lb/h)

By utilizing a high velocity stream of gas, along with the powdered coating material, the HVOF spraying process creates a dense, tightly adherent coating layer on surfaces.
