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.
