HVOF            

quick enquiry

High Velocity Oxy Fuel (HVOF) devices are a subset of flame spray. There are two distinct differences between conventional flame spray and HVOF. HVOF utilizes confined combustion and an extended nozzle to heat and accelerate the powdered coating material. Typical HVOF devices operate at hypersonic gas velocities, i.e. greater than MACH 5. The extreme velocities provide kinetic energy which help produce coatings that are very dense and very well adhered in the as-sprayed condition.

BENEFITS :-
Low porosity (<1%)
Higher bond strength (>10000 psi)
Uniform repeatability
Low operating cost
Higher particle velocities
Stable deposition rate
Controlled coating thickness
Safety interlocks

TYPICAL HVOF APPLICATIONS :-
Hydro Power – Pelton, Seat, Runner, Francis turbine etc.
Thermal Power – Boiler tube, ID Fan, Barrel etc.
Aerospace – Landing gear
Paper Industry – Rolls
General – Shafts, Bearing, Rollers, Rings,
Valves – Ball Valve, Gate Valve etc.
