  • Patent number: 8197648
    Abstract: A method for producing a low-conductivity layer on at least one workpiece by vacuum coating is provided. The method includes operating an electrical arc discharge between an anode and a cathode of an arc source in an atmosphere containing a reactive gas. A small external magnetic field is generated to be essentially perpendicular to a target surface of a target, which is electrically connected to the cathode, to assist an evaporation process. A degree of recoating of the target surface by other coating sources in a vacuum coating installation is less than 10%, and the magnetic field is generated by a magnet system with an axially-polarized coil having a geometry similar in size to that of the target. Excitation current for the electrical arc discharge is supplied through the axially-polarized coil.
