The Combustion Wire Spray process always begins with proper surface preparation. Next, Metal-based wires are used in continuously melted in an electric arc spray or gas flame spray gun. Clean, compressed air strips droplets of molten metal from the wire depositing these particles onto the steel forming the protective coating. This sprayed metal coating is both a thermal barrier coating and a galvanic coating in one. Combustion Wire Spray protects steel for longer term depending upon the application, coating thickness and sealing.
