HVOF Gun | HVOF Spray Gun in India

1. HVOF Gun It is a thermal spray system utilizing the combustion of gases or liquid. Combustion gases such as hydrogen and liquid fuel such as kerosene are used. Fuel and oxygen mix and atomize within the combustion area under conditions that monitor the correct combustion mode and pressure required for a layer. Product Details: Air Consumption Nozzle Size Air Pressure 8-9 cfm 1.4 mm 30-50 psi HVOF Gun HVOF stands for High-Velocity Oxygen Fuel, and from its name, it's easy to deduce that this thermal spray process has got to do with using molten materials (or semi-molten materials) at a high speed on substrates. These uses in application Turbine engine fan blade mid-spans, compressor blades, turbine blade roots, bearing journals, stator and rotor disk snap diameters, landing gears, actuators, flap tracks, helicopter rotor joints, and sleeves. These power generation Industrial gas turbines, hydroelectric Pelton buckets, sand blasting nozzles, and blades, exhaust fans. The high-velocity oxy-fuel process was invented only 20 years ago, yet has thrust the thermal spray application range into areas that were once unobtainable. In HVOF spraying, a mixture of process gases, like hydrogen, oxygen, and air, is injected into the combustion chamber of the torch at high and ignited. The resulting gas velocities achieve supersonic speeds. The powder is injected into the flame and also accelerated to supersonic speed. HVOF Coating HVOF gun coating very thick coating due to high velocity in compression alternately of tension and also producing excellent bond strength. During this process mostly used coating materials are Nickel & Cobalt-based alloys, Iron-based alloys, Carbides & Cermets. For very thick coating carbide is employed in more than 6mm. HVOF spray gun is employed for high-temperature applications, chemical resistance, erosion, wear resistance sliding, and abrasive. In HVOF a mix of gaseous or liquid fuel with oxygen is fed into a combustion chamber combusted continuously and ignited. For travel of hot gases at pressure 1 MPa converging-diverging nozzles are used. Hot gases travel through a straight section and hit the component. The jet velocity at the exit of the nozzle (>1000m/s) increases the speed of sound. A powder feedstock is injected into the gas stream to accelerates the powder up to 800m/s. The stream of heated gases and powder is directed towards the surface on which coating is needed. Powder

2. partially melts and impinges on the substrate. In HVOF spray gun or thermal spray gun, the resulting coating has high bond strength and low porosity.
