  • Method and apparatus for cathodic arc ion plasma deposition
    Patent number: 8387561
    Abstract: A method and apparatus for depositing a coating material on a surface of a substrate by an ion plasma deposition process using a hollow cathode is disclosed. The cathode may be a substantially cylindrical hollow cathode. A plasma arc is formed on the outer circumference of the cathode to remove coating material from the cathode, which is then deposited on a surface of a substrate. An internal arc drive magnet is contained within the hollow bore of the cathode and cooling is provided to the magnet during operation.
    Type: Grant
    Filed: December 10, 2010
    Date of Patent: March 5, 2013
    Assignee: General Electric Company
    Inventors: Scott Andrew Weaver, William Thomas Carter, Paul Mario Marruso
