Abstract
An apparatus for coating a part with a metallic coating comprising at least two consumable electrically conductive metallic wire electrodes converging to converging point at their ends, an electric current into said wires creating an arc and melting said wire ends forming an arc ball, an atomizing gas supply supplying gas to said converging point of said wires to convert said arc ball into a molten particle stream, and a deflecting gas valve assembly disposed outwardly of said consumable wires, said deflecting gas valve assembly deflecting gas from a direction which is rotatable relative to said two wires, said deflecting gas valve assembly containing a plurality of ports relative to and behind said molten particle stream supplying a steady flow of deflecting gas thereby deflecting said molten metal particle stream radially outward towards a surface to be coated.
