HVOF GUN

• HVOF coatings are excellent for shielding components from wear and corrosion damage.
• Parts can be shielded and have wear and corrosion resistance that is superior to chromium plating by having an HVOF coating sprayed on them.
• High microhardness and good bonding are characteristics of HVOF chromium carbide coatings. These coatings are perfect for offering resistance to erosion, abrasion, and corrosion caused by solid particles at high temperatures.
• Spraying HVOF Stainless Steel on the surface results in a dense, well-bonded, and less expensive coating. In salvage and repair applications, these coatings provide defense against corrosion, cavitation, and low-temperature particle erosion.

HVOF Gun (High-Velocity Oxygen Fuel) is a thermal spray technique operating release of gas or liquid. Burst gasses to same degree as hydrogen even liquid fuel to same degree as kerosene is employed. Fuel likewise oxygen merges & atomizes enclosed by explosion enclosure beneath situations so observe accurate detonation method & pressure needed for coating. We also provide all kinds of thermal spray guns, liquid HVOF Spray gun, HVOF D-gun, thermal spray powder, tungsten carbide powder, ceramic powder, 

HVOF Guns instructed an enormously high acceleration for the layering process. This high velocity is operated to force teeny bit at an accelerated velocity earlier than effect upon substrate. During an assortment of jet procedures, elevated explosion pressure & high speed of gas fumes are calculated in elevated coating acceleration.

HVOF process’s key usefulness is that high speed procedure is composed of too elevated a coating thickness & low oxide content. Typical oxide range is owing to the quickness of small bit ingesting immediately enclosed by a warmness source. And too owing to on top downward flame temperature (approx 3000 °C) of the warmness source corresponding escorted by standby methods.

During the HVOF coating process, a high noise level (>130dBa) is generated. It is advisable to operate the system in a soundproof booth (Acoustic Chamber) which protects both personnel and the environment. Shown below is a modern Thermal Spray complete with Robot & Turntable. The sound level is reduced by 40 to 50 dBA. Customize our spray system with gun and part manipulation equipment from Shot Blaster that includes robotic manipulators, turntables, vertical and horizontal traverses, and more.

Types of HVOF Gun

• HVOF Gun (Air Cooled)- Produces quality coatings, comes with Manual (hand-held) and Automatic (machine mount) models & uses hydrogen, propane or propylene fuel.
• HVOF Gun (Water Cooled)- Produces superior coatings for critical applications, comes with Manual and Automatic models & uses hydrogen, propane, propylene, ethylene* or methane* (natural gas) fuel.

Choice of Coating Materials:- Select from an expansive variety of coating materials including purified metals, metallic alloys, metallic blends, carbide powder, & self-fluxing materials, tailored to gas or liquid fuel systems.

Fuels:- Gas-fueled techniques can utilize hydrogen, ethylene, propane, propylene, or natural gas. Liquid-fueled techniques can utilize jet-A or kerosene. Select the fuel procedure that is proper to your exhibition conditions, economics, & coating grade required.

System Options:- Choose the system arrangement that suits your funding & production conditions, with a selection of standard & customized part manipulators also gun manipulators.

HVOF coating

HVOF coating is an identical dense coating ascribable to high speed in cramming instead of pressure & furthermore produces amazing adhesive stability.
In this strategy, primarily employed coating materials are Nickel and cobalt-based alloys, Iron-based alloys, Carbide Powders & Cermets. A fantastically dense coating carbide is employed in quantity of 6mm.
HVOF spray gun is employed for high-temperature utilization, chemical resistance, rust, & wear resistance sliding.
In HVOF gallimaufry of gaseous in preference to liquid fuel with oxygen is foraged into discharge enclosure combusted always & ignited. For expedition of burning gasses at strain, 1 MPa converging-diverging nozzles are engaged. Hot gasses travel via an explicit quarter & impinge on the segment.
In HVOF coating process & thermal spray gun advantages, fuel has existing gasses like hydrogen, methane, propane, acetylene, & natural gasses. And liquid fuel is like kerosene.
The jet speed at entrance of nozzle (>1000m/s) improves the acceleration of sound. A powder feedstock is insinuated into gas streamlet to rev powder capable of 800m/s.  The stream of desirable gasses & powder is orchestrated toward exterior on which coating is required. Powder partly melts & encroaches on substrate. In HVOF or thermal spray gun, the resultant coating holds lofty bond stability & quiet porosity.
HVOF coating mayhap thick 6mm - 12mm. This regularly utilized material such as ceramic & metallic layers. HVOF is numerous prosperous for the coating of carpet materials (WC-Co).
