Abstract
A method and apparatus for uniformly cladding a metal wire with a coating of a second metal is provided. The metal wire to be coated is preheated in a non-oxidizing atmosphere to a temperature slightly less than the melting point of the metal coating. The metal coating is present as a molten metal in an atomization chamber. A source of preheated, pressurized, non-oxidizing gas is utilized to inject such gas into spray nozzles. Each spray nozzle also receives molten metal that is drawn into and atomized in the nozzle. The molten metal is thusly sprayed onto the metal wire moving through the atomization chamber.
