Technology
During operation, the material being sprayed continuously melts in the center of spray gun nozzle under the action of flame created by the combustion of acetylene-oxygen mixture. The result is a heat source with temperature of over 3000 ℃ generated by gas flow.
By means of atomizing gas such as compressed air or nitrogen, drop-shaped particles of molten metal are blown out of melting zone and directed onto the prepared workpiece surface.
Wire flame spraying is one of the most common spraying methods, allowing to obtain ultra-high quality coatings. In the automotive industry, over a hundred tons of molybdenum are sprayed onto shift forks, timing rings and piston rings each year.
