ABSTRACT:
A cathode contact device is provided for providing particle deposition from an anode source onto a target surface of a working piece. The working piece has a first electrically conductive continuous contact surrounding the target surface. The cathode contact device includes a second electrically conductive continuous contact adapted for frictionally contacting the first contact along a continuous path located on the first contact. The second contact further has an inner periphery defining an aperture for passing therethrough the particles onto the target surface. Additionally, the cathode contact device includes a circuit for electrically coupling the second contact to an electrical current supply.
