• Coating material in the form of single wire
• Cord or powder is melted in an Oxy-fuel gas flame
• Molten material is atomized by compressed air
• Accelerates towards specially prepared substrate to form dense strongly adherent coating
• Flame spray process carried out correctly is called a "cold process" (relative to the substrate material being coated)
• As the substrate temperature can be kept low during processing avoiding damage, metallurgical changes
• Distortion to the substrate material

• The metal wire is fed concentrically into the flame
• Melted and atomized by the compressed air
• The molten droplets are propelled towards a prepared surface where they solidify and bond to the substrate to form a coating
• By controlling the rate of feed of the wire through the flame
• The melt and atomization of metals with various melting points can be controlled

• It can spray most of metals which are available in wire forms.

• Plasma is an electrically conductive gas containing charged particles
• When atoms of a gas are excited to high energy levels, the atoms loose hold of some of their electrons and become ionized producing a plasma containing electrically charged particles - ions and electrons
• High frequency arc is ignited between an anode (nozzle) and a cathode (electrode)
• Process gases (generally mixtures of Argon, Nitrogen, Hydrogen and Helium) flowing between them is ionized to become a plume of hot plasma gas that exceed the temperature of 6, 600 ^oC to 16, 600 ^oC (12, 000 ^oF to 30, 000 ^oF)
• When the coating substrate to produce a strongly adherent coating
• The work piece remains cool because the plasma is localized at the gun
• Plasma Spray is perhaps the most flexible of all of the thermal spray processes as it can develop sufficient energy to melt any material, the number of coating materials that can be used in the plasma spray process is almost unlimited

• The combustion powder process is similar to the combustion wire process
• Except that it has the advantage of using powder materials as the coating feedstock, which allows for a much wider range of coating material options
• Use of powder allows for a greater degree of freedom for spray gun manipulation
• Flame spray process is only limited by materials with higher melting temperatures than the flame can provide or if the material decomposes on heating
