High Velocity Oxygen Fuel (HVOF) coating

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 in the stream and deposit onto a components surface exceeding the speed of sound.

This provides coating characteristics of:

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

Materials Deposited

Celcoat, 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 * Chrome carbide * Nickel alloys
* Cobalt alloys       * Ceramic alloys   * Stainless steels

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

Typical Applications where HVOF excels include corrosion resistance; high wear resistance; sliding and abrasion; oxidation and corrosion.


For many years Celcoat (Based in Rotherham, near Sheffield) has been servicing many industries using this the HVOF process such as power generation, oil and gas processing, paper and pulp, steel rolling, glass processing, pump and valve manufacturers, railway and sea transportation to name a few.

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.
