METHOD AND INSTALLATION FOR THE VACUUM COLOURING OF A METAL STRIP BY MEANS OF MAGNETRON SPUTTERING
The method involves creating a plasma in a gas close to a metal strip (2) so as to generate radicals and/or ions acting on the strip, where the strip passes above counter electrodes (3, 3`) in a vacuum chamber (1). Each electrode has a surface moving in rotation and/or translation with respect to th...

| Zusammenfassung: | The method involves creating a plasma in a gas close to a metal strip (2) so as to generate radicals and/or ions acting on the strip, where the strip passes above counter electrodes (3, 3`) in a vacuum chamber (1). Each electrode has a surface moving in rotation and/or translation with respect to the strip. The surface is moved during coloring and continuously cleaned by scrapers (5, 5`) before being newly exposed to the plasma, where the scrapers are placed in the shadow of the plasma. An independent claim is also included for a vacuum coloring installation. |
