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 ...

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 ...

Plasma Transferred Arc (PTA)

The powder used in PTA cladding is normally of a metallic nature, and is injected into the system by coaxial nozzles (in coaxial technique). The interaction of the metallic powder stream and the Plasma (formed by the interaction of the gas and the arc generated between the electrode and the material to be cladded) causes melting to occur, and is known as the melt pool. This is deposited onto a substrate; moving the substrate allows the melt pool to ...

Diffusion Coating

Aluminizing has proven to be a cost effective way to increasing the resistance of metals from corrosion and ...

LT Corrosion

Wet corrosion takes place in environments where the relative humidity is fairly high. The corrosion may cause a uniform destruction or localized destruction (pitting, stress corrosion cracking) of the metal surface. The gas turbine's axial compressors operate in aggressive environmental conditions where low temperature corrosion phenomena, like wet corrosion, are very frequent. Aluminum based slurry coatings are widely used and approved for protection ...

Droplet Erosion

Gas turbines are generally considered the most cost effective and relatively environment-friendly large scale power generation technology, but their capacity as well as their thermal efficiency degrades under high ambient temperature conditions. Fogging Systems provide the most cost effective technique to recover this lost gas turbine capacity through adiabatic cooling of the gas turbine inlet air by the spraying of atomized water in the axial ...
