WST offers gas fuel HVOF spray coating system “SUPERJET-I” to spray coating powders like all powders from Tungsten carbide family, metallic, self-fluxing, etc to offer high wear, erosion, cavitations, etc resistant coating on the surface. Offered SUPERJET-I HVOF system is designed to work with Fuel (LPG/Propane), Oxygen and compressed air. The offered system is mostly use for manual HVOF coating application and thus considered as entry level of HVOF coating requirements for any job shop.

The offered SUPERJET-I HVOF system consists of SUPERJET-2700 HVOF gun, Rotameter type control panel, MJ-3100, Volumetric feed powder feeder MFD-3500 which is similar to Tafa Praxair’s 1264 , Gas control unit, air control unit and portable trolley. The offered HVOF gun SUPERJET-2700 is equivalent to Oerlikon Metco Diamondjet Type DJ-2700 HVOF spray gun.

WST SUPERJET-I HVOF SPRAY COATING EQUIPMENT

The model WST HVOF system SUPERJET-I sprays carbide powders melts in the HVOF gun SUPERJET-2700 due to combustion takes places in the gun by Oxygen & LPG/Propane fuel with compressed air as atomising source for spraying molten material on the substrate thereby generating high quality & dense coating on the surface.

REQUIREMENTS OF SUPERJET-I HVOF SYSTEM

• Entry level for small job shops with occasional surfacing coating requirement.
• Precision components for reliable coating results, designed with safety in mind.
• Economical system to suit every customer for manual coating process.
• Air cooled HVOF system to spray most of the common required coatings.
• Adaptable water cooled jacket for dense coating requirements.
• Suitable to use with fuels like LPG, Propane, Propylene, etc.

COATING PROPERTIES FROM SUPERJET-I HVOF SYSTEM

• High Bond Strength of the coating.
• Low surface roughness as sprayed.
• Optimum coating thickness.
• High deposition efficiency.
• Moderate deposition rate.
• High Hardness of the coating.
• High wear, erosion, cavitation resistant.

GAS FUEL HVOF SPRAY PROCESS

The HVOF spray process efficiently combusts oxygen and a gaseous fuel to produce high kinetic energy with controlled heat input. The coating material, in powder form, is introduced into the flame and uniformly heated by the hot gas stream to a molten or semi-molten condition. The flame and powder are accelerated by a nozzle (air cap) to produce supersonic gas and particle velocities, which propel the powder particles toward the substrate to be coated.
