The Wire (or Rod) Flamespray (Combustion Wire Spray) process utilises a set of drive rolls powered by an air turbine, pneumatic or electric motor to draw a single metal/alloy wire through the Flamespray gun. At the gun nozzle, fuel gas of acetylene, propane, LPG or hydrogen is mixed with oxygen in specific volumetric proportions using a siphon plug and lit to create a flame, which is then shaped at the gun’s air cap by compressed air. The metal wire is fed concentrically into the flame, melted and atomized by the compressed air, and the molten droplets are propelled towards a prepared substrate where they quickly solidify and bond to the substrate to assimilate the coating.
