Metallization process is carried out using a stream of hot obtained by oxidising fuels – normally propane, or acetylene – and then introducing the feedstock as a wire. A jet of compressed air eventually atomizes that wire’s part which is melting in the meantime, pushing the molten particles towards the substrate. This technique has a variation making where the powder is used as a material to be applied instead of a wire.
