ABSTRACT:
A vacuum plasma coating apparatus comprises a plasma torch arranged in a low pressure chamber and displaceable along a plurality of axes relative to the part to be coated and a device for moving the part to be coated with a plurality of degrees of freedom simultaneously with the plasma torch. In order to be able to coat a plurality of parts simultaneously with great effectiveness, a device for moving the part to be coated is constructed in such manner that it can contain a plurality of parts simultaneously, the parts being movable simultaneously and/or sequentially through the plasma jet. In each case the part nearest the plasma torch is arranged in the plasma jet in such manner that this extends at least occasionally laterally beyond an outer dimension of this part and all parts to be coated move within a predetermined spray distance range when they are located in the plasma jet.
