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
Industries
- 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.
