ABSTRACT:
A process provides for the reactive treatment of workpieces in which a plasma beam is produced in an evacuated recipient. With respect to the area of the highest plasma density along the beam axis, workpieces are arranged in a radially offset manner. Fresh reactive gas is charged into the recipient and used-up gas is sucked out of the recipient. A vacuum treatment system comprises a plasma beam production arrangement, a gas inlet operatively connected with a reactive gas supply, an axially extending workpiece carrier arrangement radially set off from an axis of a plasma beam produced by the plasma beam production arrangement. The workpiece carrier arrangement mounts a rotational surface coaxial with respect to the axis of the plasma beam and a gas suction system. The process and system are used to deposit metastable layers, including cBN-layers, .alpha.-Al.sub.2 O.sub.3 layers, C.sub.3 N.sub.4 layers, and diamond layers, on the workpieces, to surface treat with reactive chemical compounds, including free radicals, and to coat.
