Abstract
A method of thermally depositing metal onto a target surface using a plasma transferred wire arc thermal spray apparatus, wherein the method includes the steps of offsetting the central axis of a consumable wire with respect to an axial centerline of a constricting orifice; and establishing and operating a plasma transferred wire arc between a cathode and a free end of the consumable wire; and melting and atomizing a continually fed free end of the consumable wire into molten metal particles and projecting the particles onto said target surface.
