Abstract
An arc coating system includes a coating chamber having a peripheral chamber wall, a top wall, and a bottom wall. The peripheral chamber wall, the top wall, and the bottom wall define a coating cavity and a chamber center. A plasma source is positioned at the chamber center wherein the plasma source comprises a central cathode rod and a plurality of cathode rods surrounding the central cathode rod. The coating system also includes a sample holder that holds a plurality of substrates to be coated. Characteristically, the sample holder rotatable about the chamber center at a first distance from the chamber center.
