High Velocity Oxygen Fuel (HVOF) coating is the process by which oxygen and a fuel gas are combined within a combustion chamber where they are ignited and combusted continuously.

This Creates a high Velocity that propels the particles, which partially melt int the stream and deposit onto a components surface exceeding the speed of sound.

HVOF coating characteristics of

  • Very low porosity
  • Exceptional wear resistance
  • Fine surface finishes
  • Optimum hardness
  • Excellent bond strenth
  • Superb corrosion resistance
  • High coating thickness

Materials Deposited

The heat and spray pressure of HVOF allows the deposition of material with high hardness characteristics that further enhance friction reduction such as:

  • Tungsten carbide
  • Cobalt alloys
  • Chrome Carbide
  • Ceramic alloys
  • Nickel alloys
  • Stainless steels

It is also a preferred technique for spraying high corrosions resistance alloys such as Hastalloy and Inconel.

Benefits of HVOF
  • corrosion resistance
  • high wear resistance
  • sliding and abrasion
  • oxidation and corrosion

  • power generation
  • oil and gas processing
  • paper and pulp
  • steel rolling glass processing
  • pump and valve manufacturers
  • railway and sea transportation

Coatings produced using HVOF have outstanding characteristics, even above other spray processes and here at Celcoat we have the technical experience and now-how to provide you with a first class service to solve all your coating requirements.
