Model HVOF - Thermal Spray System
Coatings sprayed by HVOF have superior characteristics in comparison with other thermal spray processes. In particular they show a high density, high bond strength, a great wear resistance (for carbides), an excellent corrosion resistance (for metal coatings) and high thicknesses. Flame Spray uses a liquid fuel High Pressure HVOF to spray almost oxide free metal coatings and carbides with excellent wear-resistance ...

Model ID-HVOF - Internal Diameter Thermal Spray System (ID)
The application of wear resistant coating in internal diameter (ID) has always been a big challenge for thermal spray techniques. Being Line of Sight technologies, they could coat surfaces that the torch can “see”. In the past, only APS and Flame wire torches could be mounted on extenders to enter small ID. Flame Spray is using the latest technology in miniaturize HVOF and can coat a diameter as small as 70 mm. With this ID-HVOF the ...

Air Plasma Spray System (APS)
Air Plasma Spray (APS) is the most flexible of all of the thermal spray processes as it has enough energy to melt or plasticize any material from polymers to ceramics. As feedstock it uses powder that permits the application of any kind of material. A mixture of gases (normally Argon or Nitrogen and Hydrogen) is ionized to become a plasma plume with a temperature of 6,600 °C to 16,600 °C. When the coating powder is injected into the plume, it is ...

Electric Arc System
An electric arc is used to provide the heat source by utilising two current carrying wires. As the wires are fed towards each other the electric current short circuits between the wires creating a temperature of around 4,000°C. This temperature causes the tips of the wire to melt and once molten, compressed air or inert gas is used to atomise and accelerate the feed metal towards the substrate. One of the advantages of this system is that two ...

Cold Spray System
Cold Spray is a high-rate coating process that utilizes kinetic rather than thermal energy to build-up layers of metallic materials. During the process, the powder feedstock remains well below its melting point inside supersonic nitrogen flux and are accelerated to very high velocities (200 m/s to 1000 m/s). The bonding between coating and substrate is achieved by plastic deformation through adiabatic shear instabilities of the powder particles that hit ...
