Abstract
A thermal metal spraying apparatus for applying a metal coating to a target surface. The apparatus provides a cathode, a wire feed stock having a free end, and a wire guide that directs the free end of the wire feedstock to a position for establishing and maintaining a plasma transferred wire arc between the cathode and the free end of the wire feedstock. The wire guide maintains at least three points of contact with the wire feedstock as the wire feedstock is fed through the wire guide.
