In wire flame spraying, the coating material is continuously melted at the centre of an oxy-acetylene flame.
With the aid of an atomizing gas such as compressed air or nitrogen, droplet-shaped spray particles are expelled from the melt region and propelled from the melt region and propelled toward the prepared work surface.
Drive rolls feed the wire through aflame spray gun to its nozzle
Typical Material Applied :
Stainless steel, carbon steel, nickel aluminide, nickel-chromium alloy, monel, nickel, brass, bronze and bronze alloy, lead, babbit, aluminum, zinc, cadmium, tin and molybdenum.
Applications :
Flame spraying with wire is a widely used method with a very high coating quality standard. In the automotive industry, several hundred tons a year of molybdenum is sprayed on shift selector forks, synchronizing rings or pistons, bearings, syncro rings crankshats…..
