| 摘要 |
<p>The present invention relates to an electric arc evaporator including an anode (1), a support (2) for the part to be coated, a cathode group with a disc -shaped cathode to be evaporated (3), a current-carrier (4) and a main screen (5), that surrounds the periphery of the cathode (3). The height of the cathode (3) is inferior at least four times to its diameter, the current-carrier (4) is bucket-shaped and is in electrical contact with the non- evaporating surface of the cathode (3) and in that the cathode and the current-carrier are surrounded by an additional magnetic screen.</p> |
