Wire Flame Spray Technology
During wire flame spraying, the coating material is continuously fed into the center of the spray gun nozzle, where it is melted by an oxy-acetylene flame.
Combustion of the oxygen-acetylene mixture generates a high-temperature flame exceeding 3,000 °C. The molten material is then atomized by compressed air or another suitable atomizing gas, such as nitrogen, producing fine molten or semi-molten particles. These particles are accelerated toward the prepared workpiece surface, where they form a dense protective or functional coating.
Wire flame spraying is one of the most widely used thermal spray processes due to its simplicity, versatility, high deposition rates, and ability to produce high-quality coatings. The technology is extensively used in the automotive industry. Significant quantities of molybdenum and other wear-resistant materials are applied annually to components such as shift forks, synchronizer rings, piston rings, and other friction and wear components.
