HVOF Gun is a thermal spray system employing combustion of gases or liquid. Combustion gases by their nature hydrogen also liquid fuels by their nature kerosene are used. Fuel & oxygen combine & atomize in no more than combustion area granting that monitor accurate combustion method also pressure required for coating.
HVOF represents High Velocity Oxygen Fuel, also from its name, it's not difficult to find that this thermal spray measure must accomplish by employing liquid materials (or semi-liquid materials) at a fast on substrates. These utilizations in application Turbine motor fan edge mid-ranges, blower sharp edges, turbine edge roots, bearing diaries, stator & rotor plate snap widths, landing gears, actuators, fold tracks, helicopter rotor joints, also sleeves. These force age Industrial gas turbines, hydroelectric Pelton basins, sand blasting nozzle, also edges, fumes fans. The high-speed oxy-fuel measure was designed just 20 years prior, and still has pushed the thermal spray application range into regions that were earlier hopeless. In HVOF spraying, a combination of cycle gases, similar to hydrogen, oxygen, & air, is infused into burning office of light at high & touched off. The subsequent gas speeds accomplish supersonic paces. The powder is infused into the fire & furthermore quickened to quick speed.
HVOF Gun required an extremely high velocity for the HVOF coating process. This heightened velocity is utilized to move the particles at a quick speed in preparation to move onto the substrate. This kind of spray process heightened combustion pressure & high velocity of gas & particle outcome in heightened coating grade.
HVOF coating process key benefits are that the high velocity of the system contains too high coating density & lowly oxide content. The lowly oxide content is ascribable to the speed of the particles consuming a minor duration in no more than warmth source. & likewise ascribable to the lower flame temperature (approx 3,000 C) of the heat source compared with standby processes.
| Air Consumption | 8-9 cfm |
| Nozzle Size | 1.4 mm |
| Air Pressure | 30-50 psi |
HVOF gun coating extremely thick coating because of high speed in pressure then again of strain and furthermore delivering fantastic bond strength. During this cycle, generally utilized coating materials are Nickel and Cobalt-based amalgams, Iron-based combinations, Carbides, and Cermets. For extremely thick coating carbide is utilized in more than 6mm.
HVOF spray gun is utilized for high-temperature applications, synthetic opposition, disintegration, wear obstruction sliding, and rough. In HVOF coating process a blend of vaporous or fluid fuel with oxygen is taken care of into a burning section combusted ceaselessly & touched off. For the movement of superheated gases at pressure 1 MPa meeting separating nozzles are utilized. Hot gases travel via a straight area & hit the part.
The fly speed at leaving of spout (>1000m/s) speeds up the sound. A powder feedstock is infused into gas stream to quicken powder up to 800m/s. The surge of warmed gases & powder is coordinated towards the surface on which coating is required. Powder somewhat dissolves & encroaches on the substrate. In an HVOF spray gun or thermal spray gun, subsequent coating has heightened bond strength & low porosity.
