Abstract:
1. Vacuum process installation with a vacuum chamber ( 1 ) for the surface working of workpieces ( 3 ) with an arc evaporator source ( 5 ) comprising an anode ( 6 ) and a first electrode ( 5 ′) which forms a target-electrode, and whereas this anode ( 6 ) and the first electrode ( 5 ′) are connected to a DC power supply ( 13 ) and that a second electrode ( 3 , 18 , 20 ) is disposed separately from the arc evaporator source ( 5 ) and the vacuum chamber ( 1 ), characterized in that the two electrodes ( 5 ′, 3 , 18 , 20 ) are connected to a bipolar pulsed power supply ( 16 ) which generates an additional discharge path.
