TH604 is applied using a twin wire arc spray process sometimes called metalizing. Two spools of TH604 wire are put on either side of our arc spray machine which then energizes one positive and the other negative, these wires strike an arc when they come within close proximity of each other at the gun head which melts the material. Dry compressed air is added which both atomizes and propels the material to the substrate. While the material is molten in the arc zone at the gun head it quickly starts to solidify in flight, the semi-molten particles are propelled at such a rate that they become a splat when they hit the substrate.
