Abstract:
An apparatus for the application of coatings in a vacuum, comprisingat least one filtered arc source comprising at least one cathode contained within a cathode chamber, at least one anode associated with the cathode for generating an arc discharge, a plasma duct in communication with the cathode chamber and with a coating chamber containing a substrate holder for mounting substrates to be coated, the substrate holder being positioned off of an optical axis of the cathode, at least one deflecting electrode electrically insulated from the plasma duct and disposed adjacent to one or more walls of the plasma duct that are not occupied by the cathode, at least one deflecting conductor disposed adjacent to the filtered arc source and the plasma duct, and at least one repelling electrode connected to the positive pole of a current source and disposed along the plasma duct at a position between the deflecting electrode and the coating chamber.
