A device for the vacuum-plasma treatment of articles comprises a vacuum chamber (1) housing an elongated anode (2), a vacuum-arc discharge cathode (3) and a support (5), in particular for an article (6) undergoing treatment, situated between the anode (2) and cathode (3). A screen (7) which is impermeable to metal ions is provided in the chamber (1) between the cathode (3) and the support (5). The support (5) is designed to hold the article undergoing treatment at both the latter's end faces (8, 9) and is provided with a current supply line (10) at each end corresponding to the respective end face (8, 9) of the article (6). The anode (2) is elongated and parallel to a line between the two end faces (8, 9) of the article (6) and has a current supply line (11) at each end. Two pairs of current supply lines (10, 11) are connected to the positive terminal of the arc power source (4) via a switch (12) and each pair of current supply lines (10, 11) can be connected in turn. |
