The HVOF Gun is a thermal spray gun employing the explosion of gases or liquid. Combustion gases behave hydrogen also liquid fuel behave kerosene are used. An HVOF Spray Gun directed a specially high velocity for the coating process. This high speed is operated to thrust particles at supersonic velocity earlier than impact onto the substrate. In the HVOF Coating process high explosion pressure also increased velocity of gas & particle result in elevated HVOF coating differentia. HVOF process’s essential usefulness is that heightened acceleration of system contains exceptionally elevated coating thickness also lowly oxide content. The lower oxide range is a consequence of acceleration of particles consuming short period in less than warmness source. And even as a consequence of lower flame temperature (approx 3,000 °C) of warmness source approximated escorted by another process.
HVOF gun coating is a remarkably dense coating assignable to high velocity in condensing by turns of tension & even composing superior bond strength.
In this procedure, especially operated coating materials are Nickel & Cobalt-based alloys, Iron-based alloys, Carbides & Cermets. For greatly wide coating carbide is operated in excess of 6mm. We also provide liquid fuel HVOF spray gun, HVOF d-gun, HVOF Ceramic coating, HVOF tungsten carbide coating guns in India at a low price. HVOF gun price depends on the type of the HVOF Gun in India.
HVOF spray gun is utilized for high-temperature applications, chemical resistance, rust, wear resistance sliding, also abrasive.
In HVOF an assortment of gaseous or liquid power escorted by oxygen forages into an eruption compartment combusted constantly also ignited. For expedition of superheated gases at pressure 1 MPa converging-diverging nozzles are operated. Hot gases transit via a forthright quarter & impinge on components.
In HVOF & thermal spray gun coating usage, fuel can be gas viz hydrogen, propane, methane, acetylene, & raw gases. And liquid fuel viz kerosene.
The jet acceleration at the entrance of nozzle (>1000m/s) enhances the acceleration of sound. A powder feedstock is insinuated into the gas stream to rev powder up to 800m/s. The streamlet of restless gases also powder is supervised so as to approach the surface on which the coating is wanted. Powder somewhat melts & impinges on the substrate. In an HVOF spray gun or thermal spray gun, resulting coating preserves elevated bond stability even ignoble porosity.
HVOF coating is feasibly thick 6mm to 12mm. In this frequently operated material acts as ceramic & metallic layers. HVOF Gun is numerous successful for the HVOF coating process of cermet materials (WC-Co).
