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.
