ABSTRACT:
A method and apparatus for reactive plasma surfacing includes at least two electrodes between which reactive gases are passed. The reactive gases are ionized by the arc between the electrodes, creating a plasma of heated, ionized, reactive gases. The plasma is then applied to a surface to be treated, causing a chemical reaction between the plasma and the surface and resulting in a new diffusional substrate surface on the treated object. The process occurs at substantially atmospheric pressure, and may include an inert gas to shield the process from the surrounding environment.
