Patent ID: 6926811

Claim:
A method for coating objects in a vacuum chamber in which a physical vapour deposition (PVD) can be carried out, wherein the chamber comprises at least one anode means, at least one cathode and at least one magnetic field source, wherein an arc can be ignited between the at least one anode means and the at least one cathode, and wherein said cathode separates material, the at least one magnetic field can be turned relative to the at least one cathode and the objects to be coated arc arranged in the chamber, further comprising the step of the magnetic field being turned before the beginning of the coating process so that the separated material does not coat the objects to be coated in the coating process, wherein the arc for the physical deposition process is produced by means of at least two cathodes, said cathodes are constructed as substantially cylindrical tubular cathodes and the at least one magnetic field source is constructed as a permanent or coil magnet arranged in the tubular cathodes and wherein said tubular-cathodes turn about their cylinder axis during the coating process.
