HIGH VELOCITY OXY FUEL SYSTEM

Thermal Spray Wire & Welding Wires
Metal Coat HVOF 2200 and Metal Coat HVOF 2800 gun has been developed to produce high integrity coatings of metals, alloys, superalloys and carbides. Coatings sprayed with our HVOF spray gun exhibit high density, low oxide content, superior microhardness and high adhesion with excellent machinability.
Our gun can be supplied with a water-cooled front section, which allow the gun to produce higher particle velocities, maximizing coating substrate and interparticle bonding. In general, water-cooled gun also have higher coating densities, higher hardness and lower oxide content. The standard, water-cooled guns consume minimal quantities of water, with only potable (drinking water) quality required at line pressures as low as 2.76 bar (40 psi). Material spray rates, depending on gun configuration and material applied, can be as high as 150 g/min (20 lb/h), thus reducing hvof spray times. Machine-mount gun configurations are available for use with automated HVOF spray (thermal) systems as well as handheld models, which may be used with manual systems.
FEATURES AND BENEFITS
EFFECTIVE
- Produces superior coatings for wear, corrosion and other surface functions that resist the harshest of service conditions.
- Coatings are very dense, low in oxides, high hardness, low residual stress within the coating structure.
- Coatings have very high bond strengths.
- Relatively cool process, allows coating of thin-walled components.
- Choice of fuel gases and gun configurations to suit application, economics and quality requirements.
EFFECTIVE
- Smooth ‘as-sprayed’ surface finishes can be used as is for many applications, and reduces processing when post-coat machining is necessary.
- Surfaces can be machined to high finishes and tight dimensional tolerances.
- Rugged, reliable design eliminates backfire.
- Easy to maintain with modular gun hardware that is simple to remove and replace without additional tools.
- Simple powder feed start and stop on hand-held gun using built-in handle trigger.
- Gun-mounted valve core actuator lever on hand-held models easily starts and stops the flow of process gases.
ECONOMICAL
- Low process gas consumption compared to other HVOF spray guns.
- Water consumption for water-cooled guns is minimal, with only potable water quality required.
- Axial powder feed eliminates coating material build up on the extended air cap, increasing gun service life.
