Flame spray uses the chemical energy of combusting fuel gases to generate heat. Oxyacetylene torches are the most common, using acetylene as the main fuel in combustion with oxygen to generate the highest combustion temperatures. Powder, wire, or rod is introduced axially through the rear of the nozzle into the flame at the nozzle exit. The feedstock material is melted and the particles/droplets accelerated toward the surface by the expanding gas flow and air jets. An advantage of wire and rod over powder is that the degree of melting is significantly higher, producing denser coatings. In addition, the atomizing air produces finer droplets, which in turn produce finer, smoother coatings. In flame spray processes, fuel/oxygen ratio and total gas flow rates are adjusted to produce the desired thermal output. Optional air jets, downstream of the combustion zone, can further adjust the thermal profile of the flame.
